  • Use Carbon Fibers
    1,452 words
    Carbon fiber Carbon fibers are produced by using heat to chemically change rayon or acrylic fibers. Carbonization occurs at temperatures of 1000^0 C to 2500^0 C in an inert atmosphere. Carbon fibers are converted to graphite at temperatures above 2500^0 C. Carbon and graphite fibers can also be made from pitch, a residual petroleum product. Products that use carbon fibers include heat-shielding materials, aircraft fuselages and wings, spacecraft structures, and sports equipment. You can golf, ri...
  • Structure Kevlar Aramid Fiber
    781 words
    STRUCTURE Kevlar Aramid Fiber is a synthetic (man-made) material known as a Polymer. A polymer is a chain that is made up of many similar molecular groups, better known as 'monomers' that are bonded together. 'Monomers' are made up of fourteen Carbon atoms, two Nitrogen atoms, two Oxygen atoms and ten Hydrogen atoms. A single Kevlar polymer chain could possibly have anywhere from one to five million monomers bonded together. A group of polymer chains can be organised together in a fiber. How the...
  • Invention Of Paper

    One of the most important inventions of all time was the invention of gunpowder. "Imagine their enemy's surprise when the Chinese first demonstrated their newest invention in the eighth century AD. Chinese scientists discovered that an explosive mixture could be produced by combining sulfur, charcoal, and saltpeter (potassium nitrate). The military applications were clear. New weapons were rapidly developed, including rockets and others that were launched from a bamboo tube" (Franklin Institute)...
  • Possible Sources Of Cellulose Fibers

    The first historical mention of paper is 104 A.D. in China. The Empress of China at that time loved books and wanted to have a lot of them made. At the time everything was written on silk scrolls which were extremely expensive and time consuming to make. She wanted something cheaper and easier to use and so she asked one of her servants, a gentleman by the name of Tsi Lun to come up with an alternative. He worked for over nine years experimenting with different things and finally came up with he...
  • Damp Heat Test For Couplers With Epoxy
    2,157 words
    Everything You Ever Wanted to Know About dB But Were Afraid to Ask Telecommunications systems used electrical signals and copper wire to transmit voice messages long before lasers, light waves and fiber optic cable. To describe and measure power levels in electrical systems, telecommunication engineers used the standard unit of decibels to express gain or loss and relative power levels. Meanwhile, scientists working with fiber optic signals were using units of milliwatts (mW) to determine the am...

Good portions of these are combinations of synthetic fibers woven or threaded together to make a final product. These synthetic fibers are a large group of polymers. Synthetic polymers offer more possibilities, since they can be designed with molecular structures that impart properties for desired end uses. All fibers are ploy-something or polymers. That means they are long strings of repea...
  • Handmade Chain Line Paper
    465 words
    I once saw a futuristic movie about a little girl who finds a book, "a real book", she gasps, "made out of paper". In the future world of this movie, all books had been confiscated from homes and libraries and were converted into electronic files. The books could still be read, but not held. To me, this was more of a horror movie than science fiction! Part of my love of books comes from feeling the paper and hearing the rustle of the pages as they are turned. With the increasing use of the Inter...
