车用纤维增强热塑性塑料技术进展

摘要

Along with advancement of automotive industry, the demands of fiber-re inforced thermoplastics increase greatly in the world and technology of making fiber-re inforced thermoplastics enters into a new stage of rapid development.The variety of new techniques continue to emerge such as direct(or in-line) compounding and molding of long-fiber reinforced thermoplastics (D-LFT), induction heating the mould cavity to improve the surface quality of long-fiber reinforced thermoplastics(LFT) mouldings,LFT concentrates,fiber reinforced composites based on in-situ polymerized macrocyclic polyes ter oligomers,special glass fiber and sizing agent for use in LFT,etc.An overview and information related to these latest technologies are provided, which can be reference to exploit the fiber-reinforced thermoplastics for vehicle-use.%随着汽车工业的发展,纤维增强热塑性塑料的需求大幅增长,其制造工艺技术也进人了快速发展期.诸如直接(在线)配料长纤维增强热塑性塑料(D-LFT)、为改进长纤维增强热塑性塑料(LFT)模制品表面质量而采取的模具型腔感应加热、LFT母粒、基于环状齐聚酯原位聚合的纤维增强复合材料、LFT专用玻璃纤维与表面浸润剂等新技术不断涌现.对这些最新的工艺技术进展作一综述,为开发车用纤维增强热塑性塑料提供参考.
