长玻纤增强热塑性复合材料阻燃改性及老化性能研究进展

摘要

综述了近几年来长玻璃纤维(LGF)增强热塑性复合材料的发展现状,重点以聚丙烯为例,介绍了纤维含量、分布及纤维与基体之间相容性等因素对LGF增强热塑性复合材料性能的影响;重点以尼龙6为例,对LGF增强热塑性复合材料的阻燃改性及老化性能的相关研究进行了阐述.最后对未来LGF增强热塑性复合材料改性及抗老化研究的重点和方向进行了展望.%The recent development of long glass fiber (LGF) reinforced thermoplastic composites (LFT) were summarized,the effects of fiber content,distribution and compatibility between the fiber and matrix on the properties of LGF reinforced thermoplastic composites were introduced based on the polypropylene,the flame-retardant modification and aging properties of LGF reinforced thermoplastic composites were discussed taking nylon 6 for representative,and the emphases and directions of research on the modi-fication and anti-aging of LGF reinforced thermoplastic composites were also reviewed.
