Abstract

An investigation into the mechanical behaviour of microwave cured glass - epoxy composites was canied out and results compared with those of thermally cured composites. Microwave curing of a glass-fibre reinforced bi-functional epoxy resin system (LY556MY95 1) was carried out in a custom-built, multi-mode, industrial microwave cure equipment operating at a frequency of 2450 MHz. Through tensile, compression and flexural strength tests, it was demonstrated that, while the mechanical properties of microwave cured composites compared well with those of the thermally cured ones, the microwave curing process, per se, resulted in a significant reduction in the process cycle time and power consumption.
