Abstract: Glass fiber/epoxy composites were thermally conditioned at 50°C, 100°C, 150°C, 200°C and 250°C temperatures for different times and then immediately quenched directly in ice-cold water from each stage of conditioning temperature and time. The polymerization or de-polymerization by thermal conditioning and the de-bonding effect by concurrently following thermal shock in polymer composites are assessed in the present study. The short-beam shear tests were performed at room temperature on the quenched samples to evaluate the value of inter-laminar shear strength of the composites. The short conditioning time followed by thermal shock resulted in reduction of shear strength of the composites. The strength started regaining its original value with longer conditioning time. Conditioning at 250°C temperature and thereafter quenching yielded a sharp and continuous fall in the shear strength.
