    Bending Property of Carbon Fiber Reinforced Polystyrene Shape Memory Composite

      摘要
    • 摘要: 为了提高聚苯乙烯形状记忆聚合物的弯曲性能,制备了碳纤维增强聚苯乙烯形状记忆复合材料,并对其弯曲回复性能和弯曲性能进行了测试分析.结果表明:碳纤维增强聚苯乙烯形状记忆复合材料具有很好的形状回复性能,当回复时间在6 min以前其弯曲回复率高于聚苯乙烯的,最大回复率达98%;25 ℃时该复合材料承受的最大弯曲载荷约为聚苯乙烯的145%,达113 N,45 ℃时约为聚苯乙烯的108%,达39 N;塑性失效后复合材料的承载能力优于聚苯乙烯.

       

      Abstract: A kind of carbon fiber reinforced polystyrene shape memory polymer composite was developed for improving the stiffness of polystyrene shape memory polymer.The bending recoverability and bending property of the composite were investigated.The results indicate that the bending recoverability of the composite was higher than that of polystyrene and the maximum recovery ratio reached 98%.The maximum bending load of the composite was 113 N,about 145% of that of the polystyrene at 25 ℃.And it was 39 N,about 108% of that of the polystyrene at 45 ℃.The carrying capacity of the composite was super than that of the polystyrene after plastic failure.
