介绍了激光－载荷联合作用下碳纤维／环氧树脂编织复合材料单边缺口板断裂的实验和理论研究。实验测量了断裂阈值曲线，并结合显微观察确定了三种断裂模式：热应力、热减薄和热击穿模式。获得了热应力模式断裂的理论判据，与实验结果基本吻合。该判据建立了断裂临界条件下热－力和几何参数与材料性能参数之间的关系。 The experimental and theoretical studies on the fracture of unilateral notched plates of carbon fiber / epoxy braided composites under laser-load interaction are introduced. The fracture threshold curve was measured experimentally, and combined with microscopic observation, three kinds of fracture modes were determined: thermal stress, thermal thinning and thermal breakdown mode. The theoretical criterion of thermal stress mode fracture is obtained, which is in good agreement with the experimental results. The criterion establishes the relationship between thermal-force and geometrical parameters and material performance parameters under critical fracture conditions.
