摘要
通过单向流动法对含胶预成型体进行了渗透率的测试。分别研究了含胶量、铺层角度、注射压力以及注射温度对渗透特性的影响规律。结果表明,含胶量对渗透特性有影响,且不同的铺层结构有不同的影响规律。对于玻璃纤维(0,90)经编织物,渗透率随含胶量的增加呈先增后减再增的趋势,而注射压力与注射温度的影响不大,可以忽略。
An experimental investigation is carried out to deal with the permeability of preform with resin by applying the unidirectional saturated flow method. Several factors which affect the permeability are studied, including the rate of resin in preform, the ply stacking sequence, the injection pressure and the temperature. The results indicate that the rate of resin in preform influence the permeabiliy, and the laws for different ply stacking sequence are not the same. For glass fabric of （0,90）, the permeability increases first, then decreases, and finally increases as the increasing of resin. The injection pressure and the temperature do not have remarkable effect on the permeability.
