Abstract

This paper concerns the design and application of a cylindrical TM020 mode applicator for in-line microwave preheating of precatalysed thermosetting resin during resin transfer moulding (RTM). A 35% reduction in cycle time was achieved using such an applicator through the elimination of mould quench as cool resin was injected into a heated mould. Although this paper focuses on heating precatalysed polyester resin, the results are applicable to the in-line heating of any viscous, temperature sensitive fluid where excessive heating of the laminar boundary layers is undesirable.
