摘要

In order to clarify the mechanism of deformation and fracture of Si-Ti-C-O fiber-bonded ceramic composite materials (Tyrannohex), static tensile test of unnotched- and notched specimens at room temperature and microscopic observation using SEM were carried out, and then modelling and simulation of tensile fracture process were performed by using modified shear lag analysis, combined with Monte Carlo method. Interfacial shear strength was low, due to which interfacial debonding occurred. The debonding led to blunting of the tip of cracks made by premature fracture of fiber and matrix. Thus the fracture of fibers was not caused by propagation of cracks, but by their own defects. This composite was insensitive to notch. The characteristics of fracture behavior could be described fairly well by the proposed model and simulation method.
