摘　　要：为提高PA6/LLDPE形状记忆聚合物形状记忆材料形状回复率与回复力,在聚合物基体中连续排布超弹性TiNi丝制备复合材料。复合材料形状固定率,回复率,回复力通过控温三点弯曲试验设备测试。结果表明,复合材料的形状固定率与回复率均接近100%,与基体相比复合材料形状回复力则提高了200%。The shape-memory composite with a continuous TiNi wire and a PA6/LLDPE shape memorypolymer blend was fabricated so as to improve shape recovery ratio and shape recovery force.The shape memory properties of the blended materials were characterized using 3-point bending test in a temperature-controlled chamber.The results show that both the ratio of shape fixity and shape recovery are close to 100%.Recovery force increase by 200%compared with the matrix.
