摘　　要：以塑胶材料熔体的流动理论为基础,结合前辈学者对熔接线的相关研究,运用模流分析工具,对熔接线的形成过程和微观特性进行了阐述,探索了模流分析联合结构分析预测纤维增强塑胶材料的熔接线强度的方法。总结了熔接线缺陷的影响因子和改善措施。This article is based on the flow theory of plastic material melts,combined with the relevant research of previous scholars on fusion lines,and uses mold flow analysis tools to elaborate on the formation process and microscopic characteristics of fusion lines.Then,a method was explored for predicting the strength of reinforced fiber plastic material fusion lines using a combined structure of mold flow.Finally,the influencing factors and improvement measures of fusion line defects were summarized.
