结合连续纤维增强热塑性聚合物复合材料(CFRTPC)、微孔发泡聚合物材料和单聚合物复合材料(SPC)，以与基体材料相同的聚合物纤维为增强相，用聚合物/超临界流体体系浸渍，可构建一种轻质、高强、好回收的微孔发泡连续纤维增强热塑性单聚合物复合材料(M-CFRT-SPC)制品。采用微孔发泡嵌件注射成型可快速制备M-CFRT-SPC制品，聚合物/超临界流体具有更好的浸渍性能，泡孔生长产生压力有助于提高界面粘结性能。本课题拟以聚丙烯(PP)为基础材料，开展M-CFRT-SPC制品的微孔发泡嵌件注射成型机理研究，着重解决如何在快速成型过程中提高基体的浸渍性能同时调控制品内部基体、增强体和微孔间界面形态结构的科学问题，研究基体、增强体和微孔多相体系的形成过程，探明物性参数、设备结构、工艺条件的影响规律，掌握基体、增强体和微孔多相体系的界面调控机制，为理想M-CFRT-SPC制品的制备提供科学基础。

Combining CFRTPC (continuous fiber reinforced thermoplastic polymer composites) , microcellular foamed polymers and SPCs (single polymer composites), we can design the M-CFRT-SPC (microcellular continuous fiber reinforced thermoplastic single polymer composite) products which have lightweight, high strength and good recyclability. The matrix and reinforcement of the M-CFRT-SPC are from the same polymer, and the impregnating matrix to the reinforcement is polymer/supercritical fluid. The M-CFRT-SPC products can be prepared rapidly by the combination of microcellular foaming and insert injection molding. The polymer/supercritical fluid has better impregnating performance and the pressure generated during cell growth helps to improve the interfacial adhesion. This project uses PP (polypropylene) as the basic material, mainly studies the mechanism of microcellular insert injection molding of M-CFRT-SPC products, and focuses on how to improve the impregnating behavior of matrix during rapid molding and adjust the internal morphology of the matrix, reinforcement and microcells. The formation process of the multiphase system of matrix, reinforcement and microcells will be inveistigated. The influence rules of the physical properties of materials, equipment structure and process conditions will be explored. The regulation mechanism for interfaces of the multiphase system of matrix, reinforcement and microcells will be studied. The research results and achievements can be the scientific basic for the preparation of the ideal M-CFRT-SPC products.
