doi:10.19491/j.issn.1001-9278.2020.12.017

Abstract

Abstract:

This paper reviewed the development evolution of fiber orientation model and also introduced the basic theoretical ideas and expressions based on the engineering applications of the fiber orientation model for long-fiber-reinforced thermoplastics （LFRTs）. The fiber orientation model was derived from the Folgar-Tucker model and then developed to an anisotropic fiber orientation and a retarding rotary evolution. Finally the ARD-RSC model and iARD-RPR model were formed to predict the fiber orientation of LFRTs. Based on the CT scanning results of the fiber orientation in the injection molded spline of long?glass?fiber?reinforced polypropylene， the prediction accuracy of the two models was studied.

Key words: long fiber, reinforcement, thermoplastics, fiber orientation model, ARD-RSC model, iARD-RPR model
