摘　　要：以玻纤(GF)和间规聚苯乙烯(sPS)树脂为原料,采用双螺杆挤出机熔融挤出造粒,制得GF增强sPS复合材料。探究了市售的6种不同种类GF对GF增强sPS复合材料性能影响,筛选出最佳种类GF,并利用扫描电子显微镜(SEM)和差示扫描量热(DSC)仪对复合材料力学性能和结晶性能进行了表征。随后,选用适合sPS的最佳种类的GF,考察了GF含量对GF增强sPS复合材料性能的影响。研究结果表明,所选6种不同种类GF中,最佳的型号是ECS11-3.0-436H;SEM结果表明,与其他5种GF相比,该GF和sPS树脂基体具有更好的界面黏合力。DSC分析结果表明,GF的种类对复合材料的冷结晶温度和熔融温度影响不大。选择ECS11-3.0-436H的GF,质量分数在0~50%范围内,随着GF用量的增加,复合材料的各项力学性能也逐步明显提高。Glass fiber(GF)reinforced syndiotactic polystyrene(sPS)composite material was prepared from GF and sPS resin by melting and blending with twin-screw extruder.The effects of 6 different kinds of GF on the properties of sPS composites were investigated,and the best kinds of GF were selected.The mechanical properties and crystallization properties were characterized by scanning electron microscopy(SEM)and differential scanning calorimetry(DSC).Then,the best kind of GF suitable for sPS was selected,and the influence of GF content on the performance of GF reinforced sPS was investigated.The results show that the best type of GF is ECS11-3.0-436H.The SEM results show that better interfacial adhesion between GF and sPS resin matrix is obtained than other 5 kinds of GF.The results of DSC analysis show that the type of GF has little effect on the cold crystallization temperature and melting temperature of the composites.Choose GF ECS11-3.0-436H,the mass fraction is in the range of 0~50%,with the increase of GF amount,the mechanical properties of the composite are also gradually improved.
