摘　　要：针对当前聚合物实际强度远低于理论强度的问题,介绍了固态挤出、固态拉伸等自增强技术的制备流程及其工艺特点。此外,通过分析固态形变过程中试样内部的微观形貌与分子构型,进一步研究聚合物基复合材料固态加工过程中的自增强机理。最后,通过归纳总结影响试样增强效果的因素,进一步探索聚合物基复合材料的性能上限,拓宽其在不同领域的高性能化应用。To solve the problem of significant difference between the actual strength and theoretical strength of polymer,the solid-state molding technology was investigated,and the self-reinforcing process characteristics of solid-state extrusion,solid-state drawing and other technologies were described in detail,which could effectively improve the mechanical strength of polymer-based composites without any reinforcement elements.Moreover,the self-reinforcing mechanism of materials was further studied through analyzing the morphology and molecular configuration of samples during the solidstate deformation.Finally,the factors affecting the reinforcement of process were summarized to explore the upper performance limit of composites and broaden the high-performance applications of self-reinforced materials in different fields.
