| 摘 要： | 采用熔体浸渍技术制备了长玻璃纤维母料(LGF/PP-g-MAH/PP)增强聚丙烯(PP)复合材料(LGF/PP)。通过双螺杆挤出机制备了同等配比的短玻纤增强聚丙烯(SGF/PP)复合材料。研究了LGF含量、环氧树脂(EP)和固化剂(2E4MZ)对LGF/PP复合材料的力学性能影响。结果表明:当LGF质量分数为35%～40%时,LGF/PP的综合力学性能最好,且明显优于同样组成的SGF/PP复合材料。EP和含固化剂(2E4MZ)的EP对LGF/PP复合材料的力学性能提高有一定的作用。SEM照片分析表明:EP的加入能改善玻纤与聚丙烯基体的界面粘接。

| Abstract: | In this paper,long glass fiber masterbatch(PP/PP-g-MAH/LGF)reinforced polypropylene composites(LGF/PP)were prepared via melt infiltration process,and also SGF/PP composites as the same ratio by twin-screw extruder was prepared.Influence of the fiber content and epoxy resin(EP)and curing agent(2E4MZ)on mechanical properties of long fiber reinforced polypropylene was investigated.The comprehensive mechanical properties of LGF/PP composites was the best when the LGF content was 35%-40%,and was also significantly better than SGF/PP composites.Epoxy resin and epoxy resin containing curing agent(2E4MZ)were propitious to the mechanical properties of LGF/PP,and SEM showed that the interface bonding strength between the GF and PP had been improved with the addition epoxy resin. |
