摘要：通过改装毛细管流变仪建立了专门的实验装置 ,研究高温高压下熔体在纤维床层中的流动行为。采用一维恒压流动实验分别测量了不饱和及饱和流动状况下玻纤毡厚度方向聚丙烯熔体的渗透率 ,考察了玻纤毡空隙率、单丝直径、针刺等几何结构对渗透率的影响。根据实验结果进一步讨论了 GMT片材熔融浸渍过程中的气泡形成以及浸渍工艺参数的选择。
A special apparatus was constructed by modifying capillary rheometer to study polymer melt flow behavior through fiber beds. One dimension constant pressure flow experiments were carried out to measure the transverse permeability of two glass fiber mats in both unsaturated and saturated flow using PP melt as permeant. The effect of mat architecture on permeability was investigated including mat porosity, fiber diameter and needles. Furthermore, selection of impregnation parameters in GMT melt impregnation was discussed according to the experimental results.
