摘要
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 fracture threshold of the woven carbon-fiber/epoxy plates with single-side notch under combined mechanical loading and heating by incident beam is studied experimentally and theoretically.The threshold curve was measured and the fracture modes were identified through the observation of microscopy, they are thermal stressing, thermal thinning and thermal puncture. For the mode of thermalstressing corresponding to lower power laser beams, a theoretical criterion of the fracture is developed basedon the analysis with fracture mechanics, in agreement with the experimental result.
