The utility model relates to a high strength composite reinforced thermoplastic composite plate. The invention relates to a thermoplastic composite material. It has three layers of structure, including the upper fabric layer and the lower fabric layer woven by blended yarn consisting of glass fiber and polypropylene fiber, and the extrusion layer formed by mixing long glass fiber and polypropylene evenly between the upper fabric layer and the fabric layer. The polypropylene composite plate reinforced by one-way fabric combination long fibre has a tensile strength, flexural strength, modulus and impact strength increased by more than 80% along the direction of fabric glass fibre compared with the long fibre reinforced plate. The strength and modulus of PP composites reinforced by two-way fabrics with long glass fibers are increased by more than 60% in the same two directions as that of glass fibers in fabrics. The upper and lower fabric layers of the invention are made of glass fibers, which are fluidity for longer glass fibers, can be strengthened in a certain part according to need, and the middle layer is made of long glass fibers, thus ensuring its basic strength.

一种聚丙烯复合材料板
本专利技术涉及一种热塑性复合材料,特别是涉及一种高强度组合增强热塑性复合材料板。
技术介绍
玻纤增强聚丙烯复合材料由于质量轻、强度高、耐热性好、易回收等优点,在汽车零部件、建筑材料、包装材料等方面获得了广泛的应用。特别是汽车塑料件制造中,以长玻纤和长玻纤毡增强的聚丙烯材料用于成型很多的结构件和半结构件,如保险杠骨架、座椅骨架、仪表台骨架、车下体护板、前端框架等。长玻纤增强料以粒料或板材形式提供,可以注塑或模压成型制品,由于纤维长度长,增强效果较短玻纤料大大提高;长玻纤毡和连续玻纤毡增强料以板材提供,模压成型制品,由于纤维长、毡有整体结构,强度和冲击性能最好,但材料流动性差,所需的模压压力大。以毡增强的料适合制造要求高强度、高抗冲的结构件或半结构件,而长玻纤增强料适合成型大面积、结构更复杂、薄壁的部件。有时对于一些部件需要进行局部增强,或某一方向增强,如保险杠骨架沿长度方向增强,前端框架上部支撑横梁增强,则显得不适用。
