单向连续碳纤维-玻璃纤维层间混杂增强环氧树脂基复合材料的力学性能
|
摘要
为了研究连续单向纤维的层间混杂方式对复合材料力学性能及破坏方式的影响,采用碳纤维-玻璃纤维体积比为1∶1,以拉-挤成型法制备了具有不同层间混杂结构的连续单向纤维增强环氧树脂基复合材料,并研究了不同层间混杂结构的连续单向碳纤维-玻璃纤维增强环氧树脂基复合材料的力学性能及破坏形式。结果表明:具有层间混杂结构的复合材料抗拉强度处于纯碳纤维/环氧树脂复合材料和纯玻璃纤维/环氧树脂复合材料之间,复合材料的拉伸断裂方式为劈裂;具有层间混杂结构的复合材料的层间剪切强度均优于纯碳纤维/环氧树脂复合材料和纯玻璃纤维/环氧树脂复合材料,复合材料的剪切断裂方式为层间断裂。
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 interlaminar hybrid structure.The volume ratio of carbon fiber and glass fiber was 1∶1 in the composites.The results show that the tensile strength of composites with interlaminar hybrid structure is between carbon fiber/epoxy composites and glass fiber/epoxy composites,and the tensile fracture mode is cleavage.The interlaminar shear strength of composites with interlaminar hybrid structure is better than carbon fiber/epoxy composites and glass fiber/epoxy composites,and the shear fracture mode is interlaminar fracture.
