Beschreibung
Zusammenfassung:	The invention discloses a polypropylene fiber cloth composite board which is of a three-layer structure, the upper layer and the lower layer are reinforced polypropylene films, the middle layer is microcellular foaming polypropylene, and the reinforced polypropylene films are attached to the upper surface and the lower surface of the microcellular foaming polypropylene through hot working to formthe polypropylene fiber cloth composite board. And the performance of the prepared product can reach the shore hardness D level. The tensile strength, the bending strength and the impact strength of the composite material are greatly improved. The comprehensive performance of composite material is improved. Requirements of military industry, automobiles, spaceflight and the like are met. The application range is wide. 本发明公开了一种聚丙烯纤维布复合板，其采用三层结构，上层和下层为增强型聚丙烯膜，中间层为微孔发泡聚丙烯，通过热加工将增强型聚丙烯膜附在微孔发泡聚丙烯上下表面形成聚丙烯纤维布复合板。所制的产品的性能都能达到邵氏硬度达到D级。大幅度提升复合材料的拉伸强度、弯曲强度和冲击强度。提高复合材料的综合性能。满足军工、汽车、航天等要求，适用广泛。
