【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。更多还原

【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.更多还原
