Brief introduction:
The use of new composite materials dates back to ancient times. Straw reinforced clay and reinforced concrete, which have been used for hundreds of years, are made of two materials. In the 1940s, due to the needs of the aviation industry, the development of fiberglass reinforced plastics (commonly known as glass reinforced plastics), since the emergence of the composite name. Since the 1950s, carbon fiber, graphite fiber and boron fiber have been successively developed with high strength and high modulus. The 1970s saw the emergence of aramid fibers and silicon carbide fibers. These high strength and high modulus fibers can be combined with synthetic resin, carbon, graphite, ceramics, rubber and other non-metallic matrix or aluminum, magnesium, titanium and other metal matrix, forming a composite material with its own characteristics. The specific strength of uhmwpe fiber ranks the first among all kinds of fibers, especially its corrosion resistance and aging resistance. It also has excellent high frequency sonar transmittance and corrosion resistance to seawater, many countries have used it to manufacture ships' high frequency sonar deflect cover, greatly improving the ship's mine detection and mine clearance ability. Domestically, scarlett new composiste material development represents a high level. In addition to the military field, uhmwpe also has a broad application prospect in the fields of automobile manufacturing, shipbuilding, medical equipment, sports equipment and so on. This fiber has aroused great interest and attention in developed countries
