Mechanical performance of steel-epoxy composite joints bonded with acrylic adhesives via addition of silicon carbide nanoparticles

This paper reports a study on the effect of silicone carbide nanoparticles on the adhesion strength of steel–glass/epoxy composite joints bonded with two-part structural acrylic adhesives. The introduction of nano silicon carbide in the two-part acrylic adhesive led to a remarkable enhancement in the shear and tensile strength of the composite joints. The shear and tensile strengths of the adhesive joints increased with adding the filler content up to 1.5 wt%, after which decreased with adding more filler content. SEM micrographs revealed that addition of nanoparticles altered the fracture morphology from smooth to rough fracture surfaces
