This paper compares the lap shear strengths of three types of random glass fibre reinforced thermoplastic matrix composite joined by adhesives using microwave energy. Variable-frequency microwave (VFM) (2-18 GHz) facilities are used to join 33 wt % random glass fibre reinforced low-density polyethylene composite [LDPE/GF (33%)], 33 wt % random glass fibre reinforced polystyrene composite [PS/GF (33%)] and 33 wt % random glass fibre reinforced nylon 66 composite [nylon 66/GF (33%)]. With a given power level, the composites were exposed for various times to microwave irradiation. The primer or coupling agent used was a 5 min two-part adhesive.

The present study deals with the characterization of the polymeric materialsviz.,nylon-66 and 30% glass fibre reinforced nylon-66 (GF Nylon-66) by employing FTIR and thermal measurements. The complete vibrational band assignment made available for nylon-66 and GF nylon-66 using FTIR spectra confirm their chemical structure. FTIR spectroscopy provides detailed information on polymer structure through the characteristic vibrational energies of the various groups present in the molecule. The thermal behavior of nylon-66 and GF nylon-66 essential for proper processing and fabrication was studied from TGA and DTA thermograms. The thermal stability of the polymers was studied from TGA and the activation energy for the degradation of the polymeric materials was calculated using Murray-White plot and Coats-Redfern plot. The polymer with high activation energy is more thermally stable. GF nylon-66 is found to be more thermally stable than nylon-66. The major thermal transitions such as crystalline melting temperature (Tm) and degradation temperature (Td) of the polymers were detected from DTA curves. The melting behaviour of the polymer depends upon the specimen history and in particular upon the temperature of crystallization. The melting behaviour also depends upon the rate at which the specimen is heated. The various factors such as molar mass and degree of chain branching govern the value of Tmin different polymers.
