摘　　要：根据玻璃化转变温度匹配的原则,制备了一种层状复合、周期调制的形状记忆叠层复合材料。热塑性树脂层作为材料的可逆相,具有较低的玻璃化转变温度;纤维增强树脂层作为材料的固定相,具有较高的玻璃化转变温度,通过层层叠合的方式,采用热压罐成型工艺进行了形状记忆复合材料的制备。结果表明,材料具有较好的形状记忆性质,其形状固定率为90%~95%,形状回复率为95%左右。利用了复合材料可设计性强的特点,使材料之间进行复合或交叉结合,制造出了单一材料所不具备的形状记忆材料。Due to the its appropriate glass transition temperature(T_(g)),a kind of carbon reinforced carbonreinforced composite with exhibiting a shape memory effect is successfully fabricated using a layer-by-layer method.A thermoplastic polymer with a relatively low T_(g) served as the switching phase,while a cured epoxy with a relatively high T_(g) functioned as the permanent phase.The shape memory composite is then molded using an autoclave.The results demonstrate that the composites exhibit a high shape memory effect,with shape retention rates ranging from 90%to 95%and a shape recovery rate of 95%.By leveraging the high design properties of composites,two types of materials are combined to create a novel composite with a shape memory effect.
