Abstract: A new method named J-J method for mixed mode delamination test is fat her investigated through research mixed-mode interlaminar fracture toughness of T300/5405,T300/HD03 and T300/913 composites in this paper. The test data of J-J method is consistent with MMB method. It is converient for application. Only needing a few specimens are needed and the mixed-mode criterion of composites can be obtained by J-J Method.
Keywords: MMB method, composite, interlaminar fracture toughness, I and II mixed-mode delamination, mixed-mode failure criterion.
