摘要

采用拉-挤成型法制备单向连续碳纤维/玻璃纤维(混杂体积比1∶1)层内混杂复合材料,研究了混杂方式对复合材料力学性能及破坏机制的影响。结果表明,不同层内混杂复合材料受混杂结构的影响表现出不同的拉伸强度,但拉伸模量几乎不受混杂结构的影响;层内混杂复合材料的在层间剪切强度方面呈现正向混杂效应,其剪切破坏是树脂、界面破坏和纤维断裂的综合作用造成的,属于多级破坏。

Abstract

In order to study the effect of interlayer hybrid type of unidirectional fiber on the mechanical properties and failure form of composites,the method of pultrusion process was adopted to prepare continuous unidirectional hybrid fiber reinforced epoxy composites with different interlayer hybrid structure.The volume ratio of carbon fiber and glass fiber was fixed as 1∶1 in the composites.The results shown that the tensile strength of hybrid composites varied with the hybrid structure,but the tensile modulus was almost independent of the hybrid structure.The interlaminar shear strength of hybrid composites in different layers shown a positive hybrid effect.The shear failure of hybrid composites was an integrated action of interface,resin and fiber,and belongs to multistage failure.
