| 摘 要： | 针对2种碳纤维织物/环氧预浸料，采用热压罐工艺在不同条件下制备了变厚度层板，并通过层板内部形貌、层板厚度、纤维含量、吸胶量、织物渗透率的测试分析，研究了变厚度层板的密实过程和纤维分布的影响因素。结果表明：密实过程中树脂的二维流动导致2种织物变厚度层板厚板区的纤维含量高于薄板区；G0827单向织物的面内渗透率与厚度方向渗透率比值大于G0803缎纹织物，造成G0827织物变厚度层板的纤维分布不均匀性更大；无吸胶材料的条件下层板内纤维分布均匀，说明吸胶材料内树脂的面内流动对层板的纤维分布有很大影响。

| Abstract: | Variable thickness laminates under different conditions were prepared with autoclave process for two types of carbon fiber fabric/epoxy prepregs.The consolidating process and the influencing factors of fiber distribution for the variable thickness laminates were investigated by measuring the structure of fabric in cured laminate,laminate thickness,fiber content,bleeding quantity and permeability of fabrics.The results showed that the fiber content in thick area was higher than that in thin area for cured la... |
