摘要
采用Moldflow软件对聚醚醚酮(PEEK)型材接头的注射成形进行了设计与模流分析,从注塑流动过程和成型件质量等角度,研究了PEEK物料中填料种类与含量对注射压力、锁模力、成型件纤维取向张量分布、成型件翘曲量等的影响。结果表明,添加填料可以改善物料流动特性,玻璃纤维填料可以优化其力学阈值,高模量碳纤维可以显著增强成型件刚度、降低翘曲度,增加填料含量可以优化成型件刚度;通过本研究可以有针对性地搭配PEEK型材的填料种类和含量,保证注射成型质量。
Moldflow software was adopted to design and analyze the injection molding of joints in polyether ether ketone(PEEK)profiles.The effects of filler type and its content in PEEK matrix on the injection pressure,clamping force,fi-ber orientation tensor distribution and warpage of molding parts were analyzed in terms of the perspective of injection flow process and molding part quality.The results indicated that the introduction of fillers improved the flow characteristics of PEEK,and the incorporation of glass fiber as a filler could optimize its mechanical threshold.A high-modulus carbon fi-ber could significantly enhance the stiffness and reduce the warpage degree.The increase of filler content could optimize the stiffness of the molded parts.Based on the results obtained from this study,the type and content of filler for PEEK profile can be targeted to ensure a high quality of injection molding.
