摘要
为推进化学微发泡聚丙烯(PP)材料的实际应用,提升汽车轻量化水平,从化学微发泡的材料物性定义、结构设计、CAE仿真模拟和模流分析等方面对化学微发泡PP在汽车车门内饰板上的应用可行性进行探讨,对比了常规注塑和化学微发泡注塑的差异,提出了基于二次开模(Core-back)工艺的化学微发泡产品的结构设计和工艺要求,展望了化学微发泡工艺的应用前景。
In order to promote the practical application of chemical micro-foaming polypropylene material as a lightweight means,this paper firstly discusses the application feasibility of chemical micro-foaming on door interior panels in terms of material property definition,structural design,CAE simulation and mold flow analysis.Then,differences between conventional injection molding and chemical micro-foaming injection molding are compared.Finally,the structure design and process requirements of chemical micro-foaming products based on core-back process is proposed,and the application of chemical micro-foaming process is prospected.
