Abstract This paper studies the complex mechanical behaviour of woven carbon fiber reinforced polymer composites fabricated by Vacuum Assisted Resin Infusion technique. A strategy for modelling of woven composite using a continuum damage mechanic model is proposed in this research. Then different loading cases, including off-angle tension, punch and axial crushing of corrugated plate, were simulated and the numerical results correlate very well with experiments in terms of mechanical responses, which verifies the validity of the modelling strategy. However, it is found that simulation is greatly affected by some parameters including both material properties and model-specific parameters, such as potential fracture angle in the transverse direction, crush front softening parameter, contact penetration curve and thickness of crush trigger. All these parameters are determined and investigated in detail. Results show that impact responses of woven composites, including both in-plane and out-of-plane direction, can be predicted with enough accuracy.

不同载荷情况下平纹编织CFRP复合材料力学响应的数值和实验研究

摘要 本文研究了真空辅助树脂灌注技术制备的编织碳纤维增强聚合物复合材料的复杂力学行为。本研究提出了一种使用连续损伤力学模型对编织复合材料进行建模的策略。然后对不同的载荷情况进行了模拟，包括斜向拉伸、冲压和波纹板的轴向挤压，数值结果与力学响应方面的实验具有很好的相关性，验证了建模策略的有效性。然而，发现模拟受一些参数的影响很大，包括材料特性和模型特定参数，例如横向潜在断裂角、挤压前沿软化参数、接触穿透曲线和挤压触发器厚度。所有这些参数都被确定和详细研究。结果表明，可以足够准确地预测编织复合材料的冲击响应，包括面内和面外方向。
