TEMPERATURE DISTRIBUTION IN POLY(ETHYLENE-TEREPHTHALATE) PLATE UNDERGOING HEAT-TREATMENT - DIFFUSION INFLUENCE AND APPLICATION

In a previous paper, a model was developed to calculate energy efficie ncy and temperature profiles inside a polymer plate undergoing heat tr eatment. This model links up the radiator characteristics and the crys talline structures together with the material i.r. absorption behaviou r. Here, to validate the model, we present a comparison between numeri cal simulation and experimental results carried out on poly(ethylene t erephthalate) plates. Examples are then given which illustrate the pos sible applications of the model. Finally, simulation and experimental results on the crystalline fraction distribution inside the material a re presented.
