摘要
对不同铺设角［+θ6／-θ6］碳纤维／环氧树脂复合层板进行了断裂韧性G c 的测 试，并用扫描电镜对脱层破坏后的微观断口形貌进行了观察.通过研究，将层板的微观破断 机制同宏观力学性能相结合，讨论了其内在规律，并探讨了提高层板断裂韧性G c 的有 效途径.
+θ6／-θ6 inter lami nar fracture toughnesses of the carbon／epoxy composite laminates have been dete rm ined,The microscopic fracture surface of delamination has been observed with th e scanning electron microscope.By means of these studies,the relationship betwee n the fracture micromechanism and their mechanics property has been found,and the way to increase fracture toughness of composite laminates has been explored.
