| 摘 要： | 通过数值模拟、单因素试验研究了30 %碳纤维/30 %玻璃纤维增强复合材料对注塑制品翘曲变形的影响；通过多因素试验研究了各工艺参数，如熔体温度、注射时间、保压时间、保压压力等对制品翘曲变形的影响程度。结果表明，相比30 %玻璃纤维增强复合材料，30 %碳纤维增强复合材料对翘曲变形量的影响更小，30 %碳纤维增强复合材料的最大翘曲为4.107 mm，而30 %玻璃纤维增强复合材料的最大翘曲为5.090 mm；影响碳纤维增强复合材料翘曲变形的最显著因素是保压压力，而影响玻璃纤维增强复合材料翘曲变形的最显著因素是保压时间。

Research of Injection Molding Process for Carbon Fiber/Glass Fiber Reinforced Composite |
| |
| Abstract: | By numerical simulation and single factor experiments, the injection warpage of composites reinforced with 30 % carbon fiber or 30 % glass fiber was studied. The influence of various parameters such as melt temperature, injection time, holding time, packing pressure on the warpage was also investigated through multivariate experiments.The results showed: the warpage based on 30 % carbon fiber was lower than that based on 30 % glass fiber, with the maximum warpage being 4.107 and 5.090 mm, respectively. The most effective processing parameter for carbon and glass fiber reinforced composites was packing pressure and holding time, respectively. |
