PLA/PAE复合材料的形状记忆效应及机理研究
Mechanism and Shape-Memory Effect of PLA/PAE Composites
摘要
Abstract
PLA/PAE toughening composites are prepared and the shape-memory effect of composites after forced high-elastic deformation in low temperature are studied. The effect on shape-memory behavior of PAE contents, temperature, and stain are probed systemically. The shape recovery rate decreases with PAE contents increasing. The shape recovery rate and tensile strength recovery rate decrease with strain decreasing. When the recovery temperature is above 70℃, the shape recovery rate is above 90%. And with the shape recovery temperature increasing, the shape recovery rate dose not increase more, but the shape recovery time decreases. Therefore, a reasonable mechanism of shape memory effect is presented.关键词
