Topic of Research Seminar: Strength Improvement of Adhesive Joints Using Nanofiller Reinforcement

Abstract: Adhesive joining is an attractive alternative to conventional joining methods, such as welding and mechanical fastening. The benefits of adhesive bonding include: the ability to form lightweight, high stiffness structures; joining of different types of materials; better fatigue performance, and reduction in the stress concentrations or the effects of the heat associated with welding. However, lack of structural redundancy and moderate strength offered by adhesive joints still makes it an area of exploration for researchers as joint strength is significantly influenced by geometric, surface, manufacturing, and environmental parameters. In recent times, modification to the properties of host resin by the addition of nanofillers is a non-geometric parametric technique proven to be effective in improving the mechanical performance of adhesive joints. The conducted research aims to investigate in the non-metallic regime by performing a systematic study of the effect of graphene nanoplatelets (GNPs), multiwalled carbon nanotubes (MWCNTs) and reduced graphene oxide (RGO) addition on a high viscous, high strength structural adhesive at various weight fractions of the nanofiller addition.
