一、前言随着火箭、导弹和航天飞机等空间技术的发展,重量轻、强度高的各种复合材料大量使用在导弹弹头、壳体、仪器舱级间段和过渡段等结构部件上。尤其由连续石墨纤维作为复合材料加强剂的石墨/环氧复合材料具有卓越的机械性能,它将成为有机复合材料的主要品种。它不但可用于上述结构部件,还有可能成为卫星结构的主要材料:如卫星本体、支架、波导管、太阳能电池帆板、喇叭天线和大型抛物面天线等。这种高强度、高模量及低膨胀系数的 I. INTRODUCTION With the development of space technology such as rockets, missiles and space shuttle, various composite materials with light weight and high strength are widely used in structural components such as missile warheads, housings, instrument-class stages and transitional sections. Graphite / epoxy composites, especially made from continuous graphite fiber as a composite reinforcement, have excellent mechanical properties and will be the main variety of organic composites. It can be used not only for the above structural components but also as the main material for satellite structures such as satellites, brackets, waveguides, solar panels, horn antennas and large parabolic antennas. This high strength, high modulus and low coefficient of expansion
