Tensile test and numerical simulation for satin weave composite fastener

More Information
  • 摘要:

    缎纹编织复合材料紧固件中螺牙细节尺寸已达到细观尺度量级,若在数值模拟过程中对于螺牙采用统一的材料属性,则不能准确地模拟其真实失效模式。针对此问题,建立的紧固件螺牙有限元模型是由若干层简化缎纹编织复合材料细观结构代表体积单元堆叠而成,如此模型可包含必要的纤维分区和基体分区。对螺牙模型进行拉拔试验模拟,并基于各组分材料的失效判据,实现对紧固件破坏载荷的预报。完成了缎纹编织碳/碳复合材料单螺牙紧固件拉拔试验。模拟失效模式与真实失效模式吻合良好,二者破坏载荷误差为5.17%,验证了有限元模型的合理性。
