摘要
为了解决当前常用的工字形铺层复合材料整体性不佳的问题,通过合理设计,在普通织机上织造3种不同厚度的工字形三维机织物,并选用VARTM(真空辅助树脂传递模塑)成型工艺将工字形三维机织物制备成复合材料,同时测试了该复合材料的弯曲性能,并且对比分析了不同厚度的工字形三维机织复合材料的力学性能及其差异。结果表明:工字形三维机织复合材料的厚度对其力学性能的影响非常显著,随着工字形三维机织复合材料中间厚度的增加,复合材料的载荷、弯曲强度以及总的吸收能量都表现出越来越好的趋势。
In order to solve the problem of poor integrity of conventional laminated transverse H-shaped composites, 3D transverse H-shaped woven fabrics with three different thicknesses were fabricated with common loom based on reasonable design, and the 3D transverse H-shaped woven composites were prepared with VARTM molding process(vacuum assisted resin transfer molding process). Besides, the bending properties of the composites were tested, and comparison and analysis were made on the mechanical properties and differences of the 3D transverse H-shaped woven composites with different thicknesses. The results show that the thickness of 3D transverse H-shaped woven composites has a significant influence on its bending properties, and with the increase of interior thickness of 3D transverse H-shaped woven composites, the load, bending strength and total energy absorption of the composites take on an increasingly better trend.
