基于宏观静态损伤模型和累积矩阵损伤定律，提出了一种新的编织聚合物基复合材料(PMC)疲劳模型。所提出的损伤模型允许预测除频谱载荷之外的大范围复杂载荷情况下的疲劳寿命。对碳/环氧编织复合材料进行了0°、90°和45°三个方向的拉伸试验，以识别模型的静态和疲劳参数。不同构型的疲劳寿命预测值与已有试验结果吻合较好。其目的是将本方法应用于工业机织PMC结构的寿命预测。
A new fatigue model for woven polymer matrix compos ites (PMC) is presented, based on a combination of a macroscopic static damage model an d a cumulative matrix damage law. The proposed damage model allows for predicting fatigue lifetime for a large range of complex load cases, except for spectral loadings. Tensile t ests at 0°, 90° and 45° with respect to the warp direction performed on carbon/epoxy woven inte rlock materials are used to identify the static and fatigue parameters of the model. The pre dictions of the fatigue lifetime for different configurations agree well with available test resul t . The aim is to apply the present approach to predict the lifetime of industrial woven PMC str uctures.
