短纤维-弹性体复合材料的注射充模I．数学物理模型的建立

摘要

研究了短纤维-弹性体复合材料注射充模过程中，流动前锋处的喷泉效应、固化层及纤维用量与纤维之间相互作用等的影响，建立了薄壁拉伸试样型腔中短纤维-弹性体复合材料注射充模过程及其纤维取向分布的数学物理模型。%The effects of fountain flow in the front region,solidified layer, rfiber contents, interaction between the fibersin injection molding process were studied. The mathematicaland physical model was established on fiber orientation dis-tribution for short fiber elastomer composites.
