In composite material, the material that always can enhance matrix force to learn function is called enhance material. Be like the fibre glass in glass reinforced plastics, the carbon fiber in carbon fiber composite material, call enhance material. The fiber that uses in 40 time composite material enhances material, great majority is fibre glass. As industrial development, different period appeared in succession new fiber enhances material. The carbon fiber that high standard measures, boracic fiber was developed in 50 time; 60 time changed vitreous class status, studied fibre glass of S and R high strenth. Arrive from 70 time at present, developed early or late get together fiber of balmy acyl amine, carborundum fiber. As the amplification that uses a field, will have more new-style enhance material to come out. Make the composite material that enhances material with fibre glass at present (namely glass reinforced plastics) still take main place. Fibre glass is it is raw material with glass, the fiber of inorganic of a kind of man-made that makes below condition of high temperature melt. Use different production methods, can make all sorts of fibre glass with figuration different condition. Have in that way as successive as silk fibre glass, cotton of glass of fleeciness having an elephant and all sorts of staple fibre, its goods configuration is more varied. Fibre glass is had a series of superior performance, if pledge gently, excel in, high temperature resistant, anti-corrosive, sound absorption, heat preservation, hygroscopic low, stretchy cheap of good, price and raw material get small, dielectric protecties easily wait for an advantage, because this is considered as,enhance material admirably. Got applied extensively in electric, mechanical, metallurgy, oil, chemical industry, car, shipbuilding, plane, cold storage, building and national defence industry. In the United States Ervine was thought of 1938, company of Kang Ning fibre glass, began fibre glass industrialization to produce. The main use of the fibre glass at that time is to regard report as insulating material. 40 time is prime, accidental opportunity, the polyester colophony excessive that contains solidify agent arrived on cloth of a few glass, after pass the night miraculous happening, was born to strengthen plastic industry from now on, fibre glass begins to use as increase plastic. 2 times industry of big afterwar fibre glass grows quickly, achieve normalization. Its breed norms, applied limits and manufacturing technology get developing ceaselessly, especially the expanded to promote fibre glass industry greatly development of industry of glass reinforced plastics.
