PREDICTING THE TEMPERATURE PROFILE IN THE ROLL FORMING OF A COMMINGLED GLASS-PP WOVEN COMPOSITE

摘要

Thermal profile during the forming processes of polymer matrix composites is known to have arnsignificant effect on the associated, often undesired, deformations such as spring-in or springrnforward in the finished products. This article discusses comprehensive heat transfer finiternelement modeling of a multi-stage roll forming process on a typical thermoplastic composite, inrnorder to assist in predicting and adjusting the thermal profile of the material along the formingrnline, and therefore controlling the dimensional distortion of the finished curved part.
