摘　　要：在介绍单聚合物复合材料成型及性能研究的基础上,利用已有的塑件模型和可视化试验数据即熔体流动前沿速度变化曲线,验证Moldflow仿真结果的准确性,再对不同沟槽截面尺寸的增强相的充填进行仿真,通过对比二次注射的熔体流动长度,表征工艺参数对不同沟槽截面尺寸型腔中熔体成型特性的影响。Based on the research on the moulding and properties of single polymer composites, the existing plastic model and visualization test data, namely the front flow speed curve of melt, were used to verify the accuracy of Moldflow simulation results. The filling process of the enhanced phase with various groove cross-section size was simulated. By comparing the flow length of the secondary injection, the influence of the process parameters on the forming characteristics of the melt in different groove cross-section cavities was characterized.
