Comparative Analysis of Shear Strength of Single-Lap Adhesive Joints after "Thermal Shock"

Abstract:

The paper presents a comparative analysis of static shear strength of single-lap adhesive joints of 316L steel, before and after mechanical treatment with a coated abrasive tool. The research was of comparative nature and focused on adhesive joints subjected to variable thermal stress and adhesive joints not subjected to such shock. Adhesives based on epoxy resins were used. The results of static shear strength tests of single-lap adhesive joints for different variations of material preparing were analysed. The obtained results were analysed statistically and in compliance with relevant scientific standards. The scope of tests covered a relatively short fatigue cycle, i.e. 200 cycles in the range of temperatures between-40°C and +60°C. The main aim of the research was to determine the relation between joint strength and thermal fatigue. The paper presents conclusions resulting from the conducted research.
