The Materials of Construction ? The primary reinforcing agents used in the production of posite at the present time are glass, paper (cellulosic fiber 纖維素纖維 ), cotton, polyamide (聚酰胺 ) and other natural fibers, asbestos (石棉 ), sisal (劍麻 ), and jute (黃麻 ). Specially agents include carbon (碳纖維 ), graphite (石墨纖維 ), boron (硼砂 ), steel (鋼纖維 ) and whiskers (晶須 ) fiberglass carbon Kevlar f
