拉伸力场诱导植物纤维复合材料取向分布模型

Orientation Distribution Model of Plant Fiber Composites Induced by Extensional Field

研究了多相流中的一个热点问题-纤维悬浮流.在Folgar-Tucker(F-T)模型基础上,建立合理的修正模型去刻画非稀悬浮体系的行为,采用取向张量表征植物纤维在拉伸力场诱导下聚合物熔体中的取向行为.得出拉伸力场诱导植物纤维复合材料的取向分布与拉伸形变速率有关.

Fiber suspension flow,a hot topic in multiphase flow is studied.On the basis of Folgar-Tucker(F-T)model,a reasonable modified model was established to characterize the behavior of non-dilute suspension system,and orientation tensors were used to characterize the orientation behavior of plant fibers in polymer melts induced by extensional field.It is concluded that the orientation distribution of plant fiber composites induced by extensional field is related to the rate of tensile deformation.
