摘　　要：采用碳纤维质量含量分别为7.4%、10.7%、13.8%的三种碳玻层间混编单向织物制备了纤维增强环氧树脂复合材料,分析了该类材料的力学性能与工艺性能。结果表明:碳玻层间混编复合材料的0°拉伸模量和0°压缩模量均随碳纤维含量的提高而升高,掺入碳纤维后碳玻混杂复合材料的0°拉伸强度比纯玻纤复合材料的有所降低,但随碳纤维含量的增加而升高,碳玻层间混编复合材料的0°压缩强度则没有明显的变化规律;掺入碳纤维后,碳玻层间混编复合材料的90°拉伸强度和模量均有所下降;低碳纤维含量的碳玻层间混编单向织物具有良好的Z向渗透性能。该类新材料未来有望在风电叶片结构减重和成本优化上发挥重要作用。Carbon/glass hybrid woven unidirectional composite materials were studied for its use in wind blade in this article. Three kinds of carbon/glass hybrid woven unidirectional fabrics with carbon fiber mass content of7. 4%,10. 7%,13. 8% were fabricated into fiber reinforced composites. Mechanical properties and process properties of this kind of material were analyzed. The results indicate that,with the increase of carbon fiber content,0°tensile strength,0° tensile modulus and 0° compression modulus increased and 0° compression strength have no obvious variety regulation. After incorporation of carbon fiber,90° tensile strength and modulus decreased. Low carbon fiber content of carbon/glass hybrid woven unidirectional fabric has good process performance considering its permeability in Z direction. In the future,this kind of new material is expected to play a role in weight loss and cost optimization for the wind blade.
