本文在细观尺度上研究了2.5维层间角联锁机织复合材料在准静态拉伸下的渐进损伤。建立了考虑纤维损伤、基体裂纹和界面损伤的损伤模型。建立了预测2.5维机织复合材料强度的代表性体积单元。损伤萌生和扩展准则基于纤维纱线的Puck准则、基体的抛物面屈服准则和纤维纱线-基体界面的二次应力准则。预测了机织复合材料的拉伸应力-应变曲线和损伤演化规律。通过典型的实验对模型进行了验证。在考虑界面断裂能变化的情况下，模拟了复合材料的损伤行为，研究了界面性质对强度的影响。结果表明，纤维纱线-基体界面损伤特性对拉伸强度起着重要作用。
In this paper, the progressive damage of 2.5D layer-to-layer angle-interlock woven composites under quasi-static tension is investigated on a mesoscopic scale. A damage model is developed, considering the fiber damage, matrix crack and interfacial damage. The representative volume cell is established to predict the strength of the 2.5D woven composites. The damage initiation and propagation criteria are based on the Puck criterion for the fiber yarn, the paraboloidal yield criterion for the matrix and the quadratic stress criterion for the fiber yarn–matrix interface. The tensile stress–strain curve and damage evolution law of the woven composites are predicted. Some typical experiments are carried out to verify this numerical model. The damage behavior of the composites, where the variation of the interfacial fracture energy is taken into consideration, is simulated to study the influence of the interface properties on the strength. The results show that the fiber yarn–matrix interface damage characteristics play an important role in tensile strength.
