Abstract | [Abstract]: This paper extends the range of applications for Variable Frequency Microwave (2 – 18 GHz) (VFM) facilities to thermoplastic composites. Five thermoplastic polymer matrix composites are processed and discussed, including 33% by weight random carbon fibre reinforced polystyrene [PS/CF (33%)], and low density polyethylene [LDPE/CF (33%)]; 33% by weight random glass fibre reinforce polystyrene [PS/GF (33%)], low density polyethylene [LDPE/GF (33%)] and nylon 66 [Nylon 66/GF (33%)]. Bond strengths of the joints were shear tensile tested and results were compared with those obtained using fixed frequency (2.45 GHz) microwave processing. The primer or coupling agent used was 5-minute two-part adhesive containing 100% liquid epoxy and 8% amine, which was more readily microwave reactive than the composites themselves. The VFMF was operated under software control, which provided automatic data logging facilities. |
