Effect of incorrect mix ratio on strength of two component adhesive Butt-Joints tested at elevated temperature
The aim of this study was to determine the impact of the incorrect mix ratio on the strength of joints bonded with a commercial epoxy adhesive compo-sition. The performance of cold-cured as well as accelerated cured butt joints was monitored at elevated temperature conditions. The obtained data was...
