中文摘要：

基于石墨烯镀层随形快速热循环高比率纤维超薄制件的注塑成型，应用Moldflow软件对不同模具温度下的短玻纤维增强复合材料的快速热循环注塑成型过程进行了数值模拟，分析了不同纤维含量的熔体进入模腔后的填充行为，通过对模型内部的纤维取向张量、壁上剪切应力及冷冻因子的分析，从流动受力方面解释了高比率纤维超薄制件中纤维的分布。将单侧模具快速热循环注塑成型（RHCM）的试样在液氮条件下脆断，通过SEM观察微观结构形态，验证了模拟结果的正确性。

英文摘要：

Using rapid heat cycle molding（RHCM） based on graphene coating,the progress of short glass fiber reinforced composite melt filling into the die cavity at different temperature, were simulated by Moldflow. The filling behaviors of different content glass fiber reinforced composites were analyzed, considering fiber orientation tensor, wall shear force and frozen factor etc. Besides, the distribution of glass fiber in the thin parts were explained from the aspect of stress. And, the samples of RHCM were broken by liquid nitrogen, and the morphology of the microstructure was observed by SEM. Combining results of the experiments, the correctness of the simulation results were verified.
