最常用的复合物是玻璃增强塑料(GRP)和碳纤维增强塑料(CFRP),它们由用玻璃、碳或聚酰胺纤维增强热塑或热固树脂制成,增强材料可以是切成段的缕、纤维或是编织品,可单独使用,也可以组合使用。 世界各国的军用航空宇航部门,都在努力研制重量更轻、飞行时间更长、飞行高度更高的战斗机。美国空军部门意识到,要想在战斗机上再安装更多的智能电子器件,已受限于有限的空间,唯一的出路是采用灵巧复合物,以便把许多传感和处理器件塞进飞机的蒙皮里去,不至于增加飞机的重量和体积及影响空气动力学性能。
The most commonly used composites are glass reinforced plastic (GRP) and carbon fiber reinforced plastic (CFRP), which are made of glass, carbon or polyamide fiber reinforced thermoplastic or thermoset resins and the reinforcing material can be cut into sections, Fiber or braid, can be used alone, can also be used in combination. The military aerospace departments of all countries in the world are striving to develop fighter aircraft that are lighter in weight, longer in flight and more highly flying. The United States Air Force unit realized that more intelligent electronic devices to be installed on fighter jets have been limited to limited space, with the only alternative being the use of smart compounds to get many sensing and handling devices into the air To go there, do not increase the weight and size of the aircraft and affect the aerodynamic performance.
