| Summary: | Adhesive bonding is a prevalent method employed in the fabrication of advanced technical
products featuring intricate geometries. This research aims to examine the failure
attributes of adhesives with and without Thermoexpancel particles. Glass Fibre Reinforced
Polymer (GFRP) and Aluminium Steel Strip (Al) were bonded using 3M™ Scotch
Weld™ Epoxy Adhesive DP460 and 3M™ Scotch-Weld™ Epoxy Adhesive DP100,
mixed with varying weights of Thermoexpancel particles. The performance of these
adhesives was tested under normal room temperature conditions using a customized
Floating Roller Peel Test coupled with a Tensile Test machine. This study provides
insights into the load-displacement behaviour and failure mechanisms of the adhesives,
contributing to the understanding and optimization of debonding techniques for composite
materials. |
