摘　　要：以聚丙烯(PP)及玻璃纤维(GF)为原料,以不饱和聚脂(UP)作为界面相容剂,研究了界面相容剂用量对玻璃纤维增强PP复合材料力学性能、界面和结晶行为的影响。结果表明,加入UP,玻纤增强PP复合材料的力学性能明显提高,界面粘接性能得到很大的改善,且在UP用量为7%(质量分数)时,出现极大值;随UP用量的增加,玻璃纤维增强PP复合材料的结晶峰温度向低温偏移,并且结晶度逐渐降低。Using polypropylene（PP）and glass fiber（GF）as raw materials,unsaturated polyester（UP）as the interfacial compatibilizer,the effect of interfacial compatibilizer on the mechanical properties,interfacial adhesion and crystal behavior of the composites reinforced by glass fiber was studied.The results showed that adding UP,the mechanical property of glass fiber reinforced PP and its interfacial adhesion can be improved;when the content of UP was 7%,the best mechanical properties of PP/GF composites was observed.With the increase of the UP content,the crystallazation peak temperature of the glass fiber reinforced PP shifted to the lower one and the degree of crystallinity decreased.
