真空导入工艺参数对复合材料孔隙含量的影响
Influence of Processing Parameters on Void Content in VARI Manufacturing Techniques
摘要
Abstract
Through the experiments of VARI for making E-glass/vinyl ester composites, the influence of processing parameters on the content of voids in composite laminates was investigated and the condition of void formation was analyzed. The processing parameters including the temperature condition and vacuum pressure were studied. The result showed that the influence of vacuum pressure level on the content of voids in composite laminates was obvious, and the content of voids is lower at 80-90kPa. The influence of temperature level on voids content was notable below 20℃. Two trends are clear from experiments for the VARI process. First, the percentage of voids is higher near the vent as compared to the inlet. The second trend is that the void percentage increases through the thickness, being low near the plastic vacuum bag side and high near the mold tool side.关键词
