    "A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded

    cloth. 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 repeating chemical elements. Some fibers come from ground plants that synthesize connected units of cellulose
