Abstract

The use of infra-red heaters in the processing of thermoplastic composites is increasing due to the potential for quick process cycle times. Accurate modelling of the heating characteristics will help processors predict heat-up times for their processes and avoid the disadvantages associated with infra-red heating. This paper deals with the modelling of quartz tube infra-red heaters, taking into account both the characteristics of the emitted radiation and the absorption properties of the materials involved. Comparison of the model and experimental results shows that the model successfully predicts the heat-up rate and temperature distribution though different materials when heated using quartz tube infra-red heaters.
