摘要：
The interlaminar shear strengths of laminar materials (one- and two-directionally carbon fiber-reinforced carbon composites) are examined by 3-point bend of short beam (SB) and double-notched compression (DNC) methods. The serrated load versus displacement curve in SE test is related to multiple interlaminar shear failures. The conventional interlaminar shear strength of SE is always and significantly larger than that of DNC. However, the shear strength of SE modified on the basis of the microfracture processes and mechanisms for shear failure is in excellent agreement with that of DNC. (C) 1999 Elsevier Science Ltd.
