【摘要】：以玻璃纤维多轴向经编针织物为增强体,以环氧树脂为基体,将玻璃短纤维添加到玻纤织物增强体层之间,制备层间含有玻璃短纤维的多层多轴向经编复合材料。利用万能力学材料试验机对复合材料的层间撕裂性能进行测试和电镜扫描,对撕裂后的复合材料层间形态进行了观察,研究了玻璃短纤维对复合材料层间性能的影响。结果表明,玻璃短纤维增韧处理的复合材料层间撕裂性能明显增强,载荷-位移曲线初始斜率大,复合材料不易被以撕裂形式为主的载荷破坏。
[Abstract]:Using glass fiber as reinforcement and epoxy resin as matrix, glass staple fiber was added between glass fiber fabric reinforcement layer to prepare multi-layer multi-axial warp knitted composite containing glass staple fiber. The interlaminar tear properties of composites were measured by universal mechanical material testing machine and scanning electron microscope. The interlaminar morphology of the composites after tearing was observed and the effect of short glass fibers on the interlaminar properties of composites was studied. The results show that the interlaminar tear properties of the composites toughened by short glass fibers are obviously enhanced, the initial slope of load-displacement curves is large, and the composites are not easily destroyed by the main form of tearing load.
