摘　　要：对两件采用同种材料、同种成型工艺的碳纤维/双马来酰亚胺树脂复合材料构件进行性能验证考核,结果两件均通过相关试验,但其中一件在热载联合作用下的静力试验后的无损检测时,调节板上壁板的面板产生了大面积分层。通过对分层构件进行微观形貌观察、成分分析以及动态力学性能分析,研究了构件的分层原因,提出改进构件可靠性的建议。The properties of two carbon fiber/bismaleimide composite components made by the same material and technology were assessed and validated. The results show that the both passed the test, but large area delamination was found by NDT in one component after the statics test. The delamination cause was studied by observing the micro-morphology, analyzing the composition and dynamic mechanical properties; and then the advice to improve the reliability of the corn- ponents was put forward.
