混杂比对单向碳-玻层间混编复合材料0°压缩和弯曲性能的影响

摘要

本文研究了相同铺层方式下不同混杂比对单向碳-玻(碳纤维-玻璃纤维)层间混编复合材料的0°压缩和弯曲性能的影响.以碳-玻层间混编形式向纯玻纤织物中混入碳纤维,对复合材料的0°压缩强度、0°压缩模量、弯曲强度和弯曲模量均有一定的提高作用,三种碳纤混杂比不同的复合材料0°压缩强度较纯玻纤结构分别提高了22.72 ％、26.95％、11.43％,混杂比不同所导致的试样破坏程度也各不相同.混杂复合材料0°压缩模量随碳纤含量增加逐渐增大.三种碳纤混杂比复合材料弯曲强度基本一致,而弯曲弹性模量随碳纤含量增加逐渐增大.%According to the same layup structure,the axial compression and flexural properties of the unidirectional inter-layer carbon-glass hybrid composite with various hybrid ratios were inverstigated.The carbon fibers were introduced into the warp knitted glass fiber fabric.It is found that the carbon fibers can improve the strength and modulus of the axial compression and flexure in the hybrid composites.Compared with the pure glass fiber,the axial compressed strength of the hybrid composites with three different hybrid ratios increase by 22.72 ％,26.95 ％ and 11.43％,respectively.Different hybrid ratios bring about different damge modes.The axial compressed and flexural modulus of the hybrid composites both increase with the increase of the carbon fiber content.The flexural strength of the hybrid composites with different hybrid ratios keep consistent and increase unobviously.
