摘要(Abstract)：
采用将连续玻纤穿过模具的方式提高玻纤增强聚丙烯(PP)材料的力学性能。结果表明:当树脂基体中含有的长玻纤比例增大后,其力学性能也会增大;随着玻纤的质量分数增大至60%后,如果继续提高玻纤的添加量,则材料的力学强度上升速度将会明显变慢。模具内部的压延作用力设定在0.5～1 N,熔融增压压力设定在1.5～2.0 N之间是比较合理的;将增容剂质量分数设定在6%、模具温度为320℃时,材料可以获得最优的浸润效果与力学性能。
The mechanical properties of PP materials reinforced by glass fiber were improved by passing continuous glass fiber through molds. The results show that when the proportion of long glass fiber in the resin matrix increases, its mechanical properties will also increase. When the content of glass fiber increases to 60%, if the amount of glass fiber is further increased, the mechanical strength of the material will rise more slowly. It is reasonable to set the internal calendering force of the mold at 0.5～1 N, and the melting and pressurizing pressure at 1.5～2.0 N; the mass fraction of the compatibilizer is set at 6%, and the mold temperature is 320°, the best wetting effect and mechanical properties can be obtained.
