石墨纤维、Kevlar 49和玻璃超细纤维作为过滤和结构材料,正日益广泛用于各工业部门。先进复合材料是由在环氧树脂中加入石墨纤维或Kevlar纤维构成,这两种纤维的刚度都比玻璃纤维大得多。先进复合材料往往可制造比普通材料(如铝、钢和玻璃纤维)重量轻、强度大的结构材料。复合材料提高波音767的效率波音767是采用相当数量先进复合材料结构部件的第一架商业喷气飞机。先进复合材料比通用的铝或玻璃纤维的重量轻、强度大。由于平均每个部件的重量减轻了25％(在某些情况下,部件重量可减轻近35％),因此燃料消耗少。
Graphite fibers, Kevlar 49 and glass microfibers are increasingly used in various industrial sectors as filtration and construction materials. Advanced composites are made by adding graphite or Kevlar fibers to epoxy resins, both of which have significantly greater stiffness than glass fibers. Advanced composite materials tend to produce structural materials that are lighter and stronger than common materials such as aluminum, steel and fiberglass. Composites Boost Boeing 767 Efficiency The Boeing 767 is the first commercial jet aircraft to use a significant amount of advanced composite structural components. Advanced composite materials are lighter and stronger than common aluminum or glass fibers. Fuel consumption is reduced because the average weight of each part is reduced by 25% (in some cases, the part weight can be reduced by nearly 35%).
