摘要
使用碳纤维平纹布、玻璃纤维平纹布/环氧树脂预浸料制备了一种混合织物增强复合材料,并对其拉伸、弯曲、层间剪切性能以及导电性能进行了测试表征。结果表明,在-50-200℃,制备的混合织物增强复合材料的拉伸、弯曲强度相对纯玻璃纤维布增强复合材料下降,拉伸、弯曲模量均提高,两种复合材料的层剪强度保持不变;此外,碳纤维布预浸料的加入,降低了复合材料的密度,增加了导电性能,拓宽了玻璃布增强复合材料的应用范围。
A new type of mixed fabrics reinforced composite was made,using carbon and glass plain cloth/epoxy prepregs. The tensile,bending,shear mechanical properties and conductive property are tested. The results show that the mixed fabric enhanced composite has lower tensile and bending strength than the composite which was reinforced by the pure glass fabric,but the modules are higher,in-50 to 200 ℃. The shear test shows that both composites have the same interlaminal shear strength. Besides,adding the carbon fiber results is decrease in the composite density and but increase in property,and broaden the application of the glass fabric enhanced composites.
