长纤维增强热塑性复合材料在汽车前端模块中的应用

世界汽车材料技术发展的主要方向是轻量化和环保化。汽车塑料相对密度低,以塑代钢制作外装件可减轻汽车自重,达到节能减排目的。文章介绍了长纤维增强热塑性复合材料(简称LFT)在国内外汽车行业的应用情况以及在汽车前端模块的应用状态。对LFT的力学性能等方面也做了比较详细的介绍,并就传统钣金焊接和LFT制作的前端模块进行了各个方面的对比分析,从中得出了LFT材料在该零件开发中的应用前景是令人期盼的。最后对前端模块应用复合材料的设计开发提供了一些建议。

LFT Application in the Module Front End of Automobile

Light weight and environmental protection represent the major trend of global vehicle material technology.Plastic parts,with the advantages of lower relative density and lightweight,can reduce emission compared to steel ones.The paper introduces the application status of LFT in the global vehicle industry as well as the application of plastic Module Front End(MFE) .And the paper introduces the mechanical property of LFT mechanical in detail,making a comparison between welding MFE and LFT MFE.It shows that LFT application has prospective future.At last,some proposals are put forward for the design of LFT MFE.
