一种交织铺层结构层合板性能
|
摘要
结合复合材料自动纤维铺放(AFP)技术,提出了一种交织铺层结构层合板成型方法,制备了非交织、交织正交层合板、非交织、两向交织和四向交织准各向同性层合板复合材料,并对交织铺层结构复合材料的层间结构和性能进行了分析研究。结果表明:交织正交层合板的拉伸、压缩、弯曲性能较非交织板性能均有所下降,但其层间剪切性能有明显提高,提高幅度约为16%;随着交织铺层组厚度的增加,交织层合板的拉伸性能呈下降趋势;交织层合板的开孔后拉伸、开孔后压缩和冲击后压缩强度保持率均高于非交织板,且冲击后分层损伤面积明显低于非交织板。交织铺层结构层合板相对于普通非交织层合板具有更好的损伤容限能力。
A processing method for composite laminates with intersection ply mode was putted out in this paper based on automated fiber placement(AFP)technology. The samples of the composite laminates were prepared,including crossing,crossing intersection ply laminates and traditional,two-direction intersection,four-direction intersection ply quasi-isotropic laminates. Then,the laminate mode and mechanical properties of the composites were studied by mechanical properties testing,microscopy and ultrasonic testing(UT). The results show that the tensile,compressive,and flexural properties of crossing intersection ply laminates are lower than traditional,but the interlaminar shear strength is increased by 16%. With the deepening of intersection,the tensile properties are weaker.The open hole tension,compression and compressive residual strength after impact(CAI)residual ratio of quasiisotropic intersection ply laminates is higher than traditional. Intersection ply laminates have higher damage tolerance than normal ply laminates.
