Composites is a term used when you combine multiple types of materials into one. Composites often involve the use of plastics, plus other materials. \n\nSome examples of composites: \n\n- Composite decking materials, used instead of wood to make porches. \n- Composites used to build ships\n- Composites used in automobile bodies

CHICKEN FEATHERS\nChicken feathers are now being sorted, processed and made into many useful products. Some you really don't want to think about. The processed fibers from chicken plumage have been used in plastics, in paper pulp and textiles. They can also be used to make a polymer film that is made into thin sheets of plastic similar to cellophane. This polymer may first show up in biodegradable candy wrappers and plastic holders for six packs of beverages. It may also be used in plastics for dog food bowls and automobile dashboards. And a process has even been developed to make the quill protein 90% digestible - possibly for use in dietary supplements. So you could soon be eating a chicken quill protein bar wrapped in biodegradable chicken feather plastic wrap. Mmmm, Mmmm good!\nCar Parts from Chickens, Diane Martindale - Scientific American, April, 2000.\n\nPoultry Feathers Made Into Plastic Mulch \nBy Sharon Durham, February 24, 2005\n\nAgricultural Research Service (ARS)* scientists who have developed a method to turn chicken feathers into plastic products are continuing to bring the technology closer to the marketplace. \n\nARS chemist Walter Schmidt developed the technology to clean feathers and separate them into chopped fibers and quill pieces. Now Schmidt and fellow ARS chemist Justin Barone have developed and applied for a patent for a process to convert cleaned and chopped feather material into plastic products on a laboratory scale. Schmidt and Barone work in ARS' Environmental Quality Laboratory in Beltsville, Md. \n\nAccording to Barone, the material is made on traditional plastics processing equipment using chopped chicken feathers and other easily obtainable, naturally derived materials. The feather-derived plastic can be molded just like any other plastic and has properties very similar to commodity plastics such as polyethylene and polypropylene. This makes the feather-derived plastic a unique material for packaging or any other application where high strength and biodegradability are desired. \n\nPrevious research by Schmidt and Barone found feather fiber could be added into currently used plastics to make composites. The fibers strengthen the plastic components, and reduce the weight of the material. Currently, the additives and fillers used in plastics by the automobile industry, for example, add significant weight to car parts. Using feather fiber is a viable alternative to these additives. \n\nApproximately four billion pounds of feathers are generated each year during the poultry production process, resulting in a serious solid agricultural waste problem. This new application not only is a solution to an environmental problem, but also cost-effectively enhances the commercial and economic value of feathers.

white fillings are very technique sensiive.  There are as many different theories as to how is the best way to place composites as there are brands.  The most used technique is called the total etch technique, which is notorious for causing post op sensativity.  I hope your not getting white fillings on your molars?  ha.

Rectangular foam boards, called "blanks", are shaped into the design of the board, and then covered with layers of fiber glass and resin for strength. \n\nThis year the world's largest surfboard blank manufacturer, Clark Foam, closed it doors and caused and increase in surfboard prices around the world. It was a huge deal.\n\nPartly because of that, today there is more experimentation with different types of boards, especially epoxy, which is more durable than traditional foam and fiberglass models. The big company driving epoxy is called Surftech and a lot of big time shapers have signed on with them.\n\nLost Surfboards even makes a carbon fiber board now. It's great to see the new technology coming out, but let's hope it doesn't put all our local shapers out of business.

BONDO makes a fibreglass repair resin, you can buy it at Lowe's or Home Depot. Just don't get any of it on your hairy parts... I speak from experience here.

There are materials like curtains, sofa, cushion,etc which absorb sound are used . Rough finished and curved walls with wooden materials will absorb sound.Civil engineers know well about the materials and design the building acordingly.

I assume you mean "fiber reinforced plastics" (FRP) rather than fiberglass insulation batting.  There are a variety of processes for FRP manufacturing, but your basic ingredients are a resin and the reinforcing fibers.  Most of the resins (plastic) used are thermoset resins that use an catalyst (activator) to cause the resin to set.  In some cases the fibers are laid into or wound on a mold prior to application of the resin/catalyst.  Other processes use a "gun" to chop the fibers and apply them to the mold at the same time as the resin/catalyst.

Poly-methyl methacrylate (PMMA) is also used to make aircraft canopies for modern jets.\n\nThe Army also uses some variants of polycarbonate plastics for protective eyewear and lenses for lights.

Well, lets see ... there's plastic, steel, and nylon for sure.  \n\nAnd possibly ...adhesives, polystyrene, paint, glass (this one's a little iffy because it does occur in nature, albeit infrequently)

I work with epoxy composites. Epoxys have decent thermal conductivity and are strong, there are also a million different types of epoxys out there, so i'm sure theres a formula that would work for you. Good Luck

use YOUR SEARCH ENGINES: goggle, yahoo, Microsoft ETC ETC ETC     Type in metalized and coated polyester films [shorten to polyester films if needed]. Then use on-line encyclopedia to get market data. LAST:\nuse search engine and type in INDIA manufacturers or manufacturers of\nIndia. There you may be able to find under plastics or chemical etc

All engineering colleges offer courses in Composite Material Technology.\n\nMIT\n\nUniversity of Texas\n\nCal Tech\n\nTo name just three.\n\nLook for a University that does advanced research in this engineering discipline.

First of all, polymers are considered blends of different plastics to fit a certain usage.\n\nThermoplastic, from its name, tells us that these plastics can withstand extremely high and low temperature, so such plastics may be used for cooking and/or other things like containment of highly reactive materials.\n\nVOTE FOR BIG LINH HE NEEDS POINTS :P

it's a material used in production of the isolation plastic materials for home use. it's kinda related to the plactis, or PVC.\n\nsee this:\nhttp://dictionary.reference.com/search?q=Polyethylene

GRP is centrifugally cast reinforced plastic pipe composed of polyester resin, chopped glass filaments and quartz sand.\nThey r used in\nbulk water supply\nhydro power plants\nbore casing\nslip lining\nsubmarine pipelines.\n\nDi pipes are thin compared 2 ci pipes and hence lose its strenght due to corrosion and is not widely used.
