Kavlar-49复合材料是以芳香族聚酰胺纤维Kevlar-49为增强材,以合成树脂为基材的增强塑料(以下简称KRP)。该材料以其低密度、高强度、高模量等优异性能进入高级复合材料的行列。它的出现引起航空和宇航工业部门的极大重视,同时对减轻交通工具重量、降低能耗,提高性能有其现实意义。因此,自从七十年代初被开发出来以来,在航空、宇航、船舶、高级体育器利等部门得到越来越广泛的应用。
Kavlar-49 composite is a reinforced plastic based on aramid fiber Kevlar-49 reinforced with synthetic resin (hereinafter referred to as KRP). The material with its low density, high strength, high modulus and other excellent performance into the ranks of advanced composites. Its emergence has aroused great attention of the aviation and aerospace industry, and at the same time it is of practical significance to reduce the weight of vehicles, reduce energy consumption and improve performance. Therefore, since it was developed in the early 1970s, it has been applied more and more widely in such fields as aviation, aerospace, shipbuilding and advanced sports equipment.
