Abstract:By means of diamond microdebonding test method and the interfacial stress field finite element analysis(FE), the influence of interfacial thermal expansion mismatch between fiber and matrix on the interfacial strength was investigated. The results show that, the radial thermal mismatch has played a dominant role, with the influence of the axial thermal mismatch being relatively small. Furthermore, the interfacial thermal residual stress was also studied.
Key words: composite interfacial thermal mismatch interfacial strength
