蜂窝状三维整体机织复合材料的弯曲性能及其有限元模拟
|
摘要
为解决蜂窝状复合材料在黏合压制过程中整体性差的问题,经合理设计在普通织机上织造截面为三角形的蜂窝状三维机织物,并采用真空辅助树脂传递模塑成型工艺将蜂窝状三维机织物制备成复合材料。通过实验和Abaqus有限元模拟的方法,对比分析材料在不同加载速度下的载荷-位移曲线、最大载荷-速度曲线、最大吸能及破坏模式。结果表明,实验方法和有限元模拟得到的结果具有很好的统一性。使用模型可预测截面为三角形蜂窝状三维机织复合材料的力学性能,为高冲击损伤容限的蜂窝状三维机织复合材料优化设计提供理论参考。
In order to solve the poor integrity of common honeycomb composites made by bonding planar materials with pressing,honeycomb three-dimensional integrated woven fabric with triangle section shape were fabricated on a common loom by reasonable design. The honeycomb three-dimensional integrated woven composites were prepared by vacuum assisted resin transfer molding process. Then,after the comparison of load-displacement curves,maximum load-velocity curves,maximum energy absorption and failure modes of experiments and Abaqus finite element method simulation at different speeds,it is shown that they have better consistency. The Abaqus mode can be used to predict the mechanical properties of honeycomb 3-D woven composites with triangle section shape,and it also provides theory gaide for the honeycomb 3-D woven composites in the high impact damage tolerance.
