In the base of progressive damage method and bilinear cohesive model, destruction mode and limit
load of C/ C composite made by axial rod method under axial tension load were forecast by using user defined program
USDFLD of ABAQUS 6. 8. The experiment result and forecast result were compared. As a result, fracture mode of axial rod carbon/ carbon composite can be accurately forecast by using the method put forward in the paper.
