    • A method of molding a composite material which includes a fiber reinforcement within a resin comprises laying alternately on a mold first and second layers of fiber material pre-impregnated with uncured resin, where the resin content of the first layer is different from that of the second layer and the combination of layers gives the desired overall total volume fraction of fibers and resin in the laminate, enclosing the layers within an impervious membrane, evacuating the membrane and applying heat to the layers to flow gellate and at least partially cure the resin and during the process to allow released gasses and vapors to flow along the layers of lower resin content towards the membrane for subsequent evaluation.
    • 将包含树脂内的纤维增强材料的复合材料成型的方法包括交替地铺设在预浸渍有未固化树脂的纤维材料的第一和第二层上,其中第一层的树脂含量与第二层的树脂含量不同于第二层 层和层的组合给出层压体中纤维和树脂的期望总体积分数,将层包围在不透水膜内,抽空膜并向层施加热量以流过胶凝胶并且至少部分固化树脂,并且在 允许释放的气体和蒸气沿着较低树脂含量的层流向膜以用于随后的评估的过程。
