Hummer is the equipment for the army of our nation in the future . its fender is design of pp / gmt composite 国产悍马军车是我国下一代陆军装备，其挡泥板设计为pp / gmt材质。
2.
Our research is to design the mould arid optimize the molding parameters such as temperature and pressure and finally make the fender to meet the design requirements . also the fluidity and thermal conductivity of gmt are studied and theoretically analyzed the fluidity of gmt is studied by compressing the round shape gmt sheet under constant temperature 本课题研究的主要目的是制定模具设计方案，优化成型工艺参数(温度、压力制度等) ，研制出满足国产悍马军车挡泥板设计要求的制品；同时结合产品的研制，对gmt材料的流动性能、热传导性能进行初步的探索，为gmt制品的工业生产提供指导。
