摘　　要：介绍双螺杆挤出机各种规格的螺杆元件及3种螺杆组合,分析了不同螺杆组合方式对玻璃纤维增强尼龙66(GFRPA66)挤出工艺和材料力学性能的影响,并设计出一种适合于GFRPA66加工的螺杆组合方式。结果表明,通过适当的螺杆组合可改善GFRPA66的挤出工艺,提高材料的力学性能。The different size of screw elements and three screw assembles of co-rotating twin screw extruder were presented The influence of different screw assemble on the mechanical property of GFRPA66 and extruding process was analyzed. A type of screw assemble which could suit to GFRPA66 was designed. The results of experiments showed that proper screw assemble could improve extruding process and increase the mechanical property of GFRPA66.
