摘要
通过表面化学改性法对聚丙烯纤维(PPF)和连续玻纤(CGF)进行表面处理,分别实现表面羧基化和氨基化,随后采用混纺编织法制备PPF/CGF混纺织物,最后经压制成型制得复合材料。同时详细研究了CGF含量对PPF/CGF复合材料结构与性能的影响。结果表明:表面改性能有效增大复合材料的界面结合力。随着CGF含量的增大,复合材料的拉伸强度和弯曲强度先增大后减小,储能模量和损耗模量均呈增大趋势,聚丙烯(PP)半结晶时间明显缩短,结晶速率逐渐加快,结晶过程对温度的依赖性减小。此外,复合材料在NaOH溶液中的吸湿率高于NaCl溶液。
Polypropylene fi ber(PPF) and continuous glass fi ber(CGF) were treated by surface chemical modification to achieve surface carboxylation and amination respectively, and then PPF/CGF composites were prepared via blended weaving and compression-molding method. The infl uences of CGF content on structure and properties of the PPF/CGF composites were studied in detail. The results show that the surface modifi cation could effectively increase the interfacial bonding force of the composites. With the increase of CGF content, the tensile strength and fl exural strength of the PPF/CGF composites increase fi rst and then decrease, and the storage modulus and loss modulus increase. The half-crystallization time of polypropylene(PP) reduces obviously, the crystallization rate accelerates, and the dependence of the crystallization process on temperature reduces. In addition, the water absorption of the composite in NaOH solution is higher than that of NaCl solution.
