چکیده انگلیسی
Loading-unloading properties of three-dimensional-C/SiC composites at ambient temperature were studied by three-point bending experiments with single-edge notch beam specimens. Crack growth was examined by scanning electron microscopy. The whole propagation process of a notch consists of a transient state and a steady state. The crack growth resistance is derived based on energy evaluation by a graphical method taking into account the non-linear fracture of the composites. The maximum value of the crack growth resistance, corresponding to the transition of the notch into cracks, reaches about 303.7Â kJÂ mâ2 when the ratio of equivalent crack length to sample thickness amounts to 0.13. The energy for the steady crack growth is about 20Â kJÂ mâ2.
