Abstract

This study was conducted to optimize adhesive joining procedure for epoxy resin composite materials through investigations on correlation of curing condition with shear adhesive strength, curing mechanism analysis and fracture position observation. It was found that shear adhesive strength ranged 4 to 6MPa and could be improved 50 to 70% by increasing curing temperature from 20 to 140$^{\circ}C$. Based on FT-IR spectra analysis, formation of ether group(-$\bigcirc$-) as an evidence of curing was remarkable at the heated curing condition.
