| Abstract: | To fine weave & pierced C/C composites, at fiber/matrix and fiber bundle/matrix two different level interfaces, the push out test results are obtained using in situ interfacial strength testing instrument. Then using an interface spring element model, the finite element computer simulation methods are employed to simulate the fiber and fiber bundle push out test processes. The analysis program is written and the interface shearing strengths of different level interfaces are obtained. |

| Keywords: | C/C composite fiber(bundle)/matrix interface FEM interface shearing strength |
