| 摘 要： | 选用15 %玻璃纤维增强聚酰胺6（PA6）复合材料，根据Folgar-Tucker理论模型，研究了凸形截面零件全三维注射成型充填流动行为和纤维取向分布规律。结果表明，全三维模拟技术可以有效反映注射成型充填的流动形态和喷泉效应；凸形截面表层纤维沿剪切方向取向分布，且制品大端部分的纤维取向程度比小端部分差；3个坐标方向上的纤维取向分布非常复杂，沿x轴负方向（即充填方向），随充填长度的增加，纤维取向程度先增大后减小；沿y轴方向，随着距中心距离的增大，凸形截面小端部分的纤维取向程度由内向外逐渐增大，而大端部分的纤维取向程度先增大后减少；沿z轴方向，凸形截面小端部分的纤维取向由内向外呈增大趋势，而大端部分的纤维取向程度却逐渐减小。

| Abstract: | According to the Folgar-Tucker model,full 3D simulation of injection filling behavior and fiber orientations was studied for a sample of 15 % short glass fiber reinforced polyamide 6 with a convex cross section.It showed that full 3D technology could simulate effectively filling behavior and the fountain effect of injection molding.The fiber orientation in the skin was parallel to shearing flow,and the degree of fiber orientation in the big end of the samples was lower than in the small end.The fiber orient... |
