研究了亚麻纤维分别与玄武岩纤维和玻璃纤维(F/B和F/G)混杂质量比对混杂复合材料(B1-B3和G1-G3)的密度、力学性能和DMA性能.结果表明,随BF(玄武岩纤维)和GF(玻璃纤维)含量增加,F/G复合材料的理论密度和实际密度都增加,而F/B的理论密度降低,实际密度增大;B3的弯曲强度、弯曲模量和冲击韧性分别比B1高40.7％,64.5％和39.4％,G3的弯曲强度、弯曲模量和冲击韧性分别比G1高26.3％,48.0％和58.9％,复合材料F/G弯曲强度的比强度和储存模量的比模量与F/B相当,但F/G的冲击韧性和动态热机械性能都明显比F/B更好,同时F/G混杂体系的界面结合强度更高.SEM(扫描电子显微镜)表明亚麻纤维与UP结合较差,BF与UP的界面结合不如GF与UP,因此F/G力学性能比F/B更好.
