Abstract

This paper compares the thermal analysis of three types of random glass fiberreinforced thermoplastic matrix composites joined by adhesives using microwave energy. Fixed frequency, 2.45 GHz, microwave facility is used to join 33% by weight random glass fiber-reinforced nylon 66 {Nylon 66/GF (33%)], 33% by weight random glass fiber-reinforced low-density polyethylene composite [LDPE/GF (33%)] and 33% by weight random glass fiber-reinforced polystyrene composite [PS/GF (33%)]. With a given power level, the composites were exposed to various exposure times to microwave irradiation. The primer or coupling agent used was 5-min two-part adhesive. The heat distribution of the samples of the three types of composites was analysed and compared. The relationship between the heat distribution and the lap shear strength of the samples was also compared and discussed.
