Thermoplastic vs. Thermoset Resins (Composites)

Thermoplastic vs. Thermoset Resins (Composites) Thermoplastic  polymer  resins are extremely common, and we come in contact with thermoplastic resins constantly. Thermoplastic resins are most commonly unreinforced, meaning, the resin is formed into shapes and have no reinforcement providing strength. Examples of common thermoplastic resins used today, and products manufactured by them include: PET  - Water and soda bottlesPolypropylene - Packaging containersPolycarbonate - Safety glass lensesPBT - Childrens toysVinyl - Window framesPolyethylene  - Grocery bagsPVC - PipingPEI - Airplane armrestsNylon  - Footwear Many thermoplastic products use short discontinuous fibers as a reinforcement. Most commonly fiberglass, but  carbon fiber  too. This increases the  mechanical properties  and is technically considered a fiber reinforced composite, however, the strength is not nearly as comparable to continuous fiber reinforced composites. In general, FRP composites refers to the use of reinforcing fibers with a length of 1/4 or greater. Recently, thermoplastic resins have been used with  continuous fiber  creating structural composite products. There are a few distinct advantages and disadvantages thermoplastic composites have against thermoset composites.​ Advantages of Thermoplastic Composites There are two major advantages of thermoplastic composites. The first is that many thermoplastic resins have an increased impact resistance of comparable thermoset composites. In some instances, the difference is as high as 10 times the impact resistance. The other major advantage of thermoplastic composites is the ability reform. See, raw thermoplastic composites, at room temperature, are in a solid state. When heat and pressure impregnate a reinforcing fiber, a  physical change  occurs; not a chemical reaction as with a thermoset. This allows thermoplastic composites to be reformed and reshaped. For example, a pultruded thermoplastic composite rod could be heated and remolded to have a curvature. This is not possible with thermosetting resins. This also allows for the recycling of the thermoplastic composite at end of life. (In theory, not yet commercial). Properties and Benefits of Thermoset Resins Traditional Fiber Reinforced Polymer Composites, or FRP Composites for short, use a thermosetting resin as the matrix, which holds the structural fiber firmly in place. Common thermosetting resin includes: Polyester ResinVinyl Ester ResinEpoxyPhenolicUrethane The most common thermosetting resin used today is a polyester resin, followed by vinyl ester and epoxy. Thermosetting resins are popular because of uncured, at room temperature, they are in a liquid state. This allows for convenient impregnation of reinforcing fibers such as fiberglass, carbon fiber, or Kevlar. As mentioned, a room temperature liquid resin is easy to work with. Laminators can easily remove all air during manufacturing, and it also allows the ability to rapidly manufacture products using a vacuum or positive pressure pump. (Closed Molds Manufacturing) Beyond ease of manufacturing, thermosetting resins can exhibit excellent properties at a low raw material cost. Properties of thermoset resins include: Excellent resistance to solvents and corrosivesResistance to heat and high temperatureFatigue strengthTailored elasticityExcellent adhesionExcellent finishing (polishing, painting, etc.) In a thermoset resin, the raw uncured resin molecules are crossed linked through a catalytic chemical reaction. Through this chemical reaction, most often exothermic, the resin creates extremely strong bonds with one another, and the resin changes state from a liquid to a solid. A thermosetting resin, once catalyzed, it can not be reversed or reformed. Meaning, once a thermoset composite is formed, it cannot be remolded or reshaped. Because of this, the recycling of thermoset composites is extremely difficult. The thermoset resin itself is not recyclable, however, there are a few new companies who have successfully removed the resin through pyrolization and are able to reclaim the reinforcing fiber. Disadvantages of Thermoplastics Because thermoplastic resin is naturally in a solid state, it is much more difficult to impersonate reinforcing fiber. The resin must be heated to the melting point, and pressure is required to impregnate fibers, and the composite must then be cooled under this pressure. This is complex and far different from traditional thermoset composite manufacturing. Special tooling, technique, and equipment must be used, many of which are expensive. This is the major disadvantage of thermoplastic composites. Advances in thermoset and thermoplastic technology are happening constantly. There is a place and a use for both, and the future of composites does not favor one over the other.

Genre Is Important for Defining Works of Fiction Essay

Genre Is Important for Defining Works of Fiction - Essay Example The film, Hanna, clearly depicts characteristics of three genres: myth, superhero tales and fairy tales. According to a review of the movie by Bradshow, a Myth remains as a fictitious person, story or thing. In accordance to Jennifer, the genre of fairy tales often deals with stories that got folkloric fantasy possessing characters like fairies, elves, goblins, dwarves, plus some elements of magic or enchantment. The genres of superhero tales often contain a major character that stands out to be indestructible despite evil always trying to destroy the character. In the essay below, one will try to establish if the genre of myth exhibited in the movie Hanna more accurately reflects the truth in the film than do superhero tales and fairytales. In the movie, Hanna, the truth in the film could be extrapolated from the events related to the genre of myth. It the movie, an ex-Criminal Investigation Agent, Erik, trains her daughter in the wilds of Finland to become a ruthless assassin desti ned to fulfill on goal. The ideal setting of isolation totally contributed to the truth in the story since the father dedicated the entire girl’s life in learning to become an assassin. Furthermore, isolation from the real world provided an excellent environment for the girl to become ruthless. In having no upbringing like a normal child, the girl knew of one thing in life, to kill. By being two of them in the wild, they both learned survival tactics as they hunted for their meals. In relation to review by Rapold, the story remains more fictitious since the whereabouts of the Erik and Hanna remained unknown, even the Criminal Intelligence Agency, contributing to the truth of the story. From a critical perspective, any person that wishes to kill his or her enemy always needs to be prepared and be ready to surprise the enemy when the right time comes. Erik prepared Hanna for a single mission, to kill a Criminal Investigation Agent, Marissa. It is the above events related to the genre of myth that do bring the element of truth in the movie rather than the genres of fairytales and superhero tales. In the story, Hanna usually read Grimms fairy tales. The Grimms fairy tales often becomes associated with violent and horrific tales that became not consistent with fairy tales contributing to the truth of the story. Hanna, being a trained adolescent girl, becomes depicted in the story as a smart soldier, with stamina and strength like a well trained adult soldier. Her training remains quit fictitious to the reading since it is impossible for a girl that age to become a top notch assassin. Furthermore, Hanna had never interacted with the real world and met people apart from her father ever since she was born. In relation to a review by Rapold, it also becomes fictitious when a girl that has never killed any person in the wild turns to become a ruthless assassin in the real world. In trying to give the movie some truth in regard to the mission Hanna had been assign ed, the directors had to include some mythical elements. The director generally tries to link the character to and tries to fit it in the general society. Hanna runs away once she activates the signal to show their whereabouts to the Criminal Investigation Agency. It remains also mythical when Hanna adapts and camouflages in the society. In accordance to Bredshaw review, after Hanna becomes captured by the Criminal

SHALL WE DANCE ? LIFE AS A DANCE FLOOR? :: essays research papers

You expect a ‘comedy’ to tickle your funny bone so you can walk out chuckling. Yes, Shall We Dance does raise laughs. But - it also raises some interesting questions. The DVD says it’s ‘A New Comedy About Following Your Own Lead’ and a pun like that is bound to appeal to the individualistic age we are supposed to be living in. It does indeed – and yet, what is happiness and contentment? Is it a lovely, loving and loved spouse and all the trappings of a comfortable settled life? Can there be a sense of incompleteness in spite of having ‘everything’? Is that then ingratitude? Should one be allowed to pursue individual goals? At what cost? John (Richard Gere) and Beverly (Susan Sarandon) Clark are comfortably married. They have two children, and he a good job as a lawyer. Yet, he is not ‘happy’. He fills the void in his life by impulsively shooting out of his commuter train seat up the stairs of Miss Mitzi’s Dance School after being captivated by Paulina (Jennifer Lopez) gazing out of the school window. A clumsy, shy, reluctant dancer at first, he taps a hidden side to his personality and blossoms into an accomplished ballroom dancer. All very well, except none of his family is aware of this chrysalis bursting open in this way. In roughly one hour and forty-five minutes, the film turns all expectations and predictability on their respective heads. With all the action building up towards the climactic Chicago Tattinger Trophy who could blame you for expecting a neatly wrapped package at that point: Clark rewarded for his accomplishment, all revealed and settled? But - it is its aftermath that has much to say. Yes, there is dance as the mating ritual. Bobbie (Lisa Ann Walter), earthy, vivacious, loud, generous-hearted, is disappointed at Clark’s treatment of Rumba, â€Å"the dance of love†. Paulina with her smouldering, controlled, Latino (stereotypical?) passion sets him straight. Yes, there is the hinted sexual attraction, even tension. But - there are also the bonds forged of friendship, camaraderie and candour. Life and people are given a direction by and through dance. John Clark is able to put his life in perspective, while Paulina unearths a lost spirit to chase her dreams. Beverly, a â⠂¬Å"romantic† with her sense of romance probably buried under the laundry, jackets at the apparel division where she works and the whims of two teenage children, is very understandably miffed but finds her feet again – and how!

Cafe Amadeo Development Cooperative Essay

In September 24, 2014, Technological Institute of the Philippines (TIP) – Quezon City had a plant tour. It is one requirement in our course’s Production and Operation Management. Our two organizations that we went are in Cafe Amadeo Development Cooperative and in Tri-R Allied Industries, INC. Both of them are really exciting when we heard about those organizations that we will be going for. Our mission here is to get knowledge and to apply it for ourselves in our future work. It was very educational because we saw the processes of how they do the coffee and also the parts of the vehicle. But before all, my classmates and I met within the school at 4:30am exactly because we do not want to make us left the bus so we go ahead for our assurance. The bus leave at school at exactly 7o’clock in the morning. After traveling of almost 3 hours, we finally arrived in Cavite at 10:30 in the morning. We started to discover, observe and learn in Cafà © Amadeo Development Cooperative organization. Their exact place is at Barangay 6, Poblacion, Amadeo, Cavite. This is the logo and actual view of their business, Cafà © Amadeo has their general purpose, vision and mission. Here are they; GENERAL PURPOSE To promote the cooperative as way of life by improving the social and  economic well-being of the people. VISION The country leading cooperative that produces and distributes quality coffee. MISSION Produce and offer quality products and services through technologically advanced capabilities its members. Develop professional officers and management team encourge thrift and savings consciousness. In their organization, you should be truly honest and loyal. They held that kind of value. Mrs. Agnes, the spokes man told us that Cafà © Amadeo was started on June 28, 2002 with only 20 members. They have an investment of â‚ ±137,500.00 when Cafà © Amadeo started, but it is just bit of their money. The coffee millers and traders of Amadeo were taking the amount of coffee. Their coffee before were worth rage of â‚ ±450.00 – â‚ ±500.00 per cut. Per cut is about 1 kilo and it has coffee pod yet. The usual coffee before was too expensive but because the coffee was lack of supply, they washout the coffee. Most farmers before usually gets their livelihood in coffee, like Mrs. Agnes’ life. So they take another economical as farming pineapples and papayas because coffee was almost a year when you are harvest it. But the good news here is, the DTI, DOST, and Provincial Municipal helps their cooperative to promote their products. Their cooperative consists of Farmers, Traders, and Millers. All the members are encouraged to sell and to add capital. It has also set up five market outlets, three in Cavite, one in Paraà ±aque City and lately in San Fernando, Pampanga. From now on, the cooperative is fast growing and keeping to its mission of continually supplying best grade coffee beans and ground coffee for the entire benefit of Amadeo Coffee farmers (4,560) in general and of its members in particular. They has a different kinds of coffee and this is the, Arabica Coffee, Liberica / Baracco Roasted Coffee, Robusta, and Excelsa. Mrs.Agnes told us that Arabica Coffee is commonly in Davao, Baguio and Benguet because it springing up in high and cold areas. Liberica/Baracco Roasted Coffee produces big beans, resistant to drought. The pulp is very thick and it takes 40 days to dry. Robusta is the number 1 soluble of coffee and most preferred by coffee growers. It dries in 15 days and since the pulp easily separates from the beans, it takes least effort to clean. Excelsa, which is secondly to Baracco. Excelsa is also resistant to drought and takes 25 days to dry. With  a pulp that does not separate from the beans when milled. PROCESS OF CAFÉ AMADEO The process used by Cafà © Amadeo is continuous because there is a very high volume of nondiscrete, highly standardized output is desired and their products have almost no variety in output and no need for equipment flexibility. It is used to manufacture, produce, or process materials without interruption. It also produces greatest quantity of a product over the time. Continuous-flow production requires products for which the same level of quality can be reliably achieved as long as the process of manufacture and the ingredients are unchanged. A production worker in continuous production commonly works in rotating shifts. So that I think they used Job rotation which means having workers periodically exchange jobs to avoid having one or a few employees stuck in a monotonous job because some of the employees will be get bored from their jobs because some of the responsibility there is only putting coffees into their packages or to wait the coffee from machine. As what I remembered from the speaker, they chose Amadeo province because since then Amadeo is one of the places that already engaging in coffee farming and coffee is Amadeo’s major crop for trade. There is a very high volume of nondiscrete, highly standardized output is desired and their products have almost no variety in output and no need for equipment flexibility. Continuous-flow production requires products for which the same level of quality can be reliably achieved as long as the process of manufacture and the ingredients are unchanged. They’re also using Product layout, product layout in the sense that there is a flow in the production of coffees or there are step by step processes. From work station 1 to work station 2 and so on and so for. Cafà © Amadeo their stores are located near towns in different places in Cavite so that it can easily be seen by the travelers and also they can be easily recognized by their customers. When it comes to working condition their work places are full of ventilations and sound proof mirrors so that their workers cannot be bothered by any distractions such as heat and other factors that can affect their works. VISION To be the most preferred manufacturing solution provider MISSION AND GOALS PROFITS-To have a sustainable growth of 20% annually and to maximize profit margin. PEOPLE-Proud and Happy associates. PORTFOLIO- To be an industry market leader and game changer. PARTNERS- To be preferred name the industry. PLANET- To be an environmental friendly company. PRODUCTIVITY- Promote effective management of people time and money TRI-R ALLIED INDUSTRIES INC. PROCESS CAPABILITIES STAMPING Metal stamping presses range from 35 – 600 tons for manufacturing seat frames and automotive parts. PAINTING/PLATING Bare metal parts are pre-treated before powder coating at 240 degrees C. Aside from painting, engaged also in in-house plating. WELDING Welding process occupies a large part of automotive parts manufacturing. From thin metal sheets to form structures. Welding processes include resistance welding, arc and gas welding using welding assembly jigs. SEWING AND SEAT ASSEMBLY The company cut, saw and assembled motorcycle dual seat assembly using PVC leatherette. Pad cushion and bottom plate. FOAM INJECTION Two components chemicals are used both for automotive and motorcycle seat pads. MACHINING The in-house machining centre fabricates tool and dies. The in-house machining centres fabricate tool and dies. METAL CASTING The company also employ metal casting process using High Press Die and Ductile Iron Casting using aluminium or metal alloys. TRI-R PROCESS MAP TRI-R Inc. uses job shop processing because they are customizing metal processing shop. A job shop process creates the flexibility needed to produce a variety of products or services in significant quantities like in TRI-R they make different kinds of parts of vehicle/cars. Customization is relatively high, and volume for any one product to meet customer quality and service standards. The work force and equipment are flexible and handle various tasks. Typically, they make products to order and don’t produce them ahead of time. The specific needs of the next customer are unknown, and the timing of repeat orders from the same customer is unpredictable. Each new order is handled as a single unit–as a job. A job shop process primarily involves the use flexible flow strategy, with resources organized around the process. Most jobs have a different sequence of processing steps. The job shop is organized by process, where assembly lines or continuous flow operations are organized in a product layout. In the latter layout, equipment or work processes are arranged according to the exact steps in which the product is made and the path for each part resembles a straight line. And also TRI-R is using Product Layout processing because the layout of equipment and processes in the workstations are distributed around the needs of the end product. Each station is given a small task to complete in a certain sequence. Because according to the information that I’ve obtained TRI-R is using Product Engineering, according to the definition of Product Engineering it is the process of designing and developing a device, assembly, or system such that it is produced as an item for sale through some production manufacturing process. So that, it became my basis to say that they’re using product layout. Also they are using assembly line of production because the automobiles parts that they are processing are added as the semi-finished assembly moves from work station to work station where the parts are added in sequence until the final product is produced.

General And Special Education Teachers Face Today

There are many issues that general and special education teachers face today. The goal of both of these types of teachers should be that they try their best to make their students succeed. Teaching can be very difficult and people that are passionate about it should do it. However, many general and special education teachers face many challenges throughout their teaching careers that make teaching difficult for them. One issue that teachers lack today is lack of proper coaching from school staff when they begin teaching. Proper coaching is extremely important for new teachers to obtain during their first year in school. I believe the new teachers need coaching because most teachers learn a variety of teaching methodologies, philosophies and requirements during their undergraduate studies but they are seldom taught how to manage and structure a classroom. It is very difficult to learn the struggles of teaching in a school unless you experience it for yourself. Many new teachers are placed to work in schools without prior coaching or materials. In addition, many teachers receive necessary information and materials that are needed to teach throughout the school year, instead of having it a few weeks prior to teaching. Along with planning lessons teachers also have to learn the school’s curriculum, policies and procedures. At this time, it becomes a reality that teachers are responsible for their students’ well-being and education.
