RESEARCH DEVELOPMENT OF GLASS FIBRE REINFORCED NYLON 6 COMPOSITES

优化玻璃纤维(GF)的种类和用量、尼龙6(PA6)与GF的复合工艺,改善PA6与GF的界面结合情况,均有利于改进PA6/GF复合材料的性能。利用第三组分和GF对PA6进行协同改性也是改善PA6/GF复合材料性能的重要手段。综述了PA6/GF复合材料性能的影响因素、复合材料的复合工艺、界面处理方法和第三组分与GF对PA6的协同改性等方面的研究进展。

Research development about factors influencing property of nylon 6 （PA6） / glass fibre （GF） com- posites, compounding process of the composites, interphase treatment, and synergism modification of GF and third component on PA6 were reviewed in this study. The increase of GF content is propitious to improve mechanics and tribology property of PA6/GF composites. The improvement effect of long GF on the composites is better than that of short GF. Surface treatment of silane coupling agent, rare earths and compatibilizer on GF is conducive to improve interface combine strength, and increase integration property of the composites. Addition of nanometer SiO2 and Si3N4 into PA6/GF composites is propitious to improve mechanics and tribology property of the composites, and addition of nanometer clay is able to improve its mechanics and flame retardant property. Addition of carbon nanotubes into the composites is not only able to improve its mechanics property, but also able to improve its antistatic and flame retardant property. Addition of styrene/acrylonitrile/maleic anhydride eopolymer and polythene into the composites is conducive to depress its hygroscopicity, and addition of UHMWPE is able to improve its tribology property. Flame retardant containing phosphorus and GF have synergism effect on improvement of flame retardant property of the composites.
