通过湿热谱老化试验，研究了湿热谱老化对复合材料层压板拉伸和冲击后压缩（ＣＡＩ）强度的影响。试验结果表明，湿热老化引起严重的强度降，特别是冲击后压缩强度。老化后损伤面积不扩展或扩展很小。
The effects of aging on the CAI strength of composite laminates were investigated by means of the heat aging test. The test results show that the hot and humid aging caused serious decline in strength, especially after impact compressive strength. Damage area after aging does not expand or expand very small.
