The study examines the strength and durability of single lap joint created using the identical
epoxy adhesives (LY-556/AD 22962) that are single lap adhesively joined. As per credible
research data available, epoxy adhesives and single lap adhesively bonded joints' failure
strengths are influenced by a number of factors, and their strength can be increased using
a number of different techniques. Addition of filler material to epoxy is one of the efficient
techniques. A flexible natural raw material, cork powder is used to strengthen adhesives
and SLJs that are adhesively bonded by acting as a crack-stopping filler. However, with
change in concentration of filler, this behavior of cork powder changes.
The current work focuses on evaluating differences in the structural characteristics of
epoxy-based adhesives and adhesively bonded single lap joints at various temperatures and
cork powder concentrations. A series of simulation have been performed for investigation
of SLJs strength with LY-556 as epoxy adhesive and Aluminum 5052 as adherend. The
adhesively bonded joint is tested at different temperature ranges from 25ºC, 50ºC, 75ºC
and 100ºC with the concentration of cork powder ranging from weight percentages of 0.25,
0.5, 0.75 and 1.
