Nano-modified adhesive by graphene: the single lap-loint case

this paper addresses the performance study on, low viscosity, nano-modified adhesives by graphene. for achieving this goal, single-lap joints following astm d 5868-01 were manufactured and tested. x-ray diffraction, scanning electron microscopy and nanoindentation were employed for graphene based nanostructures characterization. the increase on joint strength was around 57% when compared against the control group. furthermore, all failures for the nano-modified adhesive were cohesive failure for the carbon fibre/epoxy composites indicating that the adhesive was tested. x-ray diffractions signatures indicate formation of nano-structures with 17-19 nm diameters. moreover, nanoindentation tests revealed a homogeneous dispersion of graphene.
