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