【摘要】 测试了5种不同规格型号的三维正交机织复合材料以及同种型号增强体与两种不同树脂基体得到的复合材料的抗拉伸、抗弯曲力学性能,并分析了其破坏模式。结果表明:三维机织复合材料能有效阻止分层破坏,且纬向的力学性能明显好于径向,其力学性能也会随树脂基体力学性能的提高而有所提高,模量的变化尤其明显。更多还原

【Abstract】 Tensile and flexural mechanical performance of five different types of 3D woven composites and one woven with two types of resin were investigated.The result indicates that 3D woven composites has an effective action to prevent delaminating destruction.The mechanical performance of weft is better than warps’,and it increases with the mechanical performance of resin matrix,especially module.更多还原
