Abstract

In this paper, four groups of shape memory composites with carbon fiber mass fraction of 28.09%, 41.87%, 53.20%, and 63.80% were prepared by vacuum infiltration hot-press forming experimental system. The effect of carbon fiber mass fraction on the shape memory properties of shape memory composites was studied. The results showed that the shape fixed rate and the shape recovered speed of composite decreased with the increase of carbon fiber mass fraction. The shape recovered rate and the maximum recovered force first increased and then decreased, and the shape recovered time increased gradually.

纤维含量对 GO-CF 增强 SMPC 形状记忆性能的影响

摘要

本文采用真空浸渗热压成型实验系统制备了四组碳纤维质量分数分别为28.09%、41.87%、53.20%和63.80%的形状记忆复合材料。研究了碳纤维质量分数对形状记忆复合材料形状记忆性能的影响。结果表明，随着碳纤维质量分数的增加，复合材料的形状固定率和形状恢复速度降低。形状恢复率和最大恢复力先增大后减小，形状恢复时间逐渐增加。
