  • 摘要: 使用自行设计的夹具对纯树脂沿纤维织物厚度方向的毛细浸渗行为进行了初步研究。通过改变温度、纤维体积分数、纤维类型以及铺层方式,研究了树脂对纤维织物的毛细浸渗规律,并研究了纤维表面浸润剂的影响。结果表明:升高温度和减小纤维含量均有利于提高浸渗速率;而铺层方式的改变对浸渗规律的影响甚小。
    Abstract: Capillary impregnation of pure resins in the transverse direction of unidirectional cloth beds was studied elementarily by using self-designed fiber holder. The effect of experiment parameters, such as temperature, fiber volume fraction, fiber types and the stacking orientation of unidirectional cloth on the velocity of the capillary impregnation was investigated. And the impregnation of the unidirectional cloth without sizing on the surface was tested. In comparison with the cloths with sizing, the capillary impregnation velocity of clothes without sizing appears to be much quick. The results show that increasing the temperature and decreasing the fiber volume fraction can both improve the velocity of impregnation. However, changing the stacking orientation of the unidirectional cloth has little influence on the impregnation behavior.
