摘　　要：通过对两种材料、两种规格的复合材料加筋板结构在损伤预制与未预制两种状态下后屈曲的耐久性试验与剩余承载能力试验研究,探讨了复合材料加筋板结构在使用载荷作用下壁板局部失稳后的耐久性和剩余承载能力,以及冲击损伤对复合材料特性的影响。A test of the post buckling durability and residual load carrying capability of composite stiffened-skin structures of two materials and two sizes under the pre-damaged and undamaged conditions was conducted. The durability and residual load carrying ability of composite stiffened-skin structures that are in local buckling under the limit load conditions and the effects of impact damages on composite properties were discussed.
