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。
Aiming at the two kinds of carbon fiber fabric / epoxy prepregs, the hot-pressed cans were used to prepare variable thickness laminates under different conditions. Through the internal morphology of the laminates, the thickness of the laminates, the fiber content, the amount of adhesive, the fabric permeability Test analysis of the thick layer thickness of the dense process and the impact of fiber distribution factors. The results show that the two-dimensional flow of resin in the compacting process results in the thickening of the two kinds of fabric layer thicker fiber board area than the sheet area; G0827 unidirectional fabric in-plane permeability and thickness direction permeability ratio greater than the G0803 satin fabric , Resulting in G0827 fabric thicker laminates fiber distribution of non-uniformity greater; no glue material under the conditions of fiber distribution within the laminates, indicating that the resin in the gel material in-plane flow of the fiber distribution of the board has a great impact .
