摘要
文中结合计算机辅助工程(CAE)及Taguchi实验设计(DOE)技术研究了玻纤含量和工艺参数对玻纤增强聚丙烯注塑制品各向异性收缩的影响。基于Taguchi DOE方法采用L18(36)正交矩阵进行了实验以优化制品的收缩,并研究了各个参数对制品收缩的影响程度。对于主实验中所选因素,纤维含量、熔体温度和保压压力对玻纤增强聚丙烯注塑制品各向异性收缩的影响较大。
Short-fiber reinforced polypropylene （PP） composites are very attractive due to their easy fabrication, economy and superior mechanical properties. Injection molding process is the main method to molding short fiber reinforced polymer （SFRP） composites. Shrinkage is one of several important indexes determining the quality of injection molded parts, and non-uniform shrinkage is a main cause of the part warpage. In this paper, computer-aided engineering（CAE） and Taguehi design of experiments（DOE） technique were combined to investigate the influence of glass fiber content and process conditions on anisotropic shrinkage in injection molded fiber reinforced PP part. An L18（36） orthogonal array design based on the Taguchi method was conducted to minimize the shrinkage of fiber reinforced PP parts, and the significance of each factor on the shrinkage was investigated. For the factors selected in the main experiments, fiber content, melt temperature affecting the shrinkage of the injection molded parts. and holding pressure were found to be the principal factors
