| 摘 要： | 复合材料由于疲劳载荷导致的损伤因素很多,它们都将导致刚度下降,这些损伤因素的相互作用,使得复合材料的损伤机理十分复杂.本文对复合材料的一些典型损伤分别从纤维复合材料的微观结构出发、提出力学模型,对纤维断裂、界面脱胶及分层导致的刚度下降用宏观力学原理进行了分析,并与实验结果进行了比较.

| Abstract: | The stiffness reduction of composite laminates due to various damages is studiod.From the viewpoint of the micro-structure of composite laminates,the stiffness reduction caused by fiber breakage,fiber-matrix debonding and dela- mination are analyzed by the approach of damage mechanics using the micro- mechanical principle which is established by the actual fracture mechanisms. |
