IMPROVE THE PERFORMANCE OF EPOXY RESIN AND POLY (VINYL BUTYRAL) AS AN ALUMINUM METAL ADHESION

Abstract

The present work is mainly concerned with study the performance of epoxy resin which blended with poly (vinyl butyral) in order to be used as adhesive for aluminum metal. A different weight ratios of poly (vinyl butyral) was blended with epoxy resin (10-90 wt %) and these blends were cured at different conditions; time (10-60) minutes and temperature (100-200 Co), different mechanical properties (shear stress, elongation and peeling stress) were carried out on the prepared samples. Box – Wilson design method was adopted to find useful relationships between the three variables [(weight ratios and curing conditions (time & temperature)] with mechanical properties shear stress, elongation and peeling stress , it was found that the best adhesive properties of the prepared sample (i.e. best mechanical properties) obtained with the weight ratio of (40) wt% epoxy resin and (60) wt% poly (vinyl butyral) while the best curing condition obtained at a temperature of 160 Co for (30) min.
