Carbon fibers restrained the matrix cracks growth and diminished the crack tip stress intensity factor.
纤维对基体开裂起抑制作用并降低了裂纹尖端的应力集中。
2
The predicted fracture stress matrix cracking stress and crack spacing just have error less than 20% with the corresponding experimental value.
预测的断裂应力、基体开裂应力和裂纹间距与实测值最大误差在20%以内。
3
The fracture mechanism of composites is matrixcrack, but the particle crack will be the main crack mechanism when the content of coarse or the flaw in the coarse increased.
