Tensile Strength Assessments of CFRP Adhesive Bonded Joint

Joining technology is widely used for assembling of aerospace and automotive structures. Compared to mechanical fastened, riveted joints and spot welds,adhesive bonding have the following advantages such as structural integrity, higher strength to weight ratio, ease of applicability, join dissimilar materials, reduced stress concentration, and improved fatigue resistance. Epoxy resin is an engineering adhesive that has outstanding mechanical and thermal properties.

Reinforcements are mostly used in the development of composite materials ranging from macro to nano-scale. Nanofillers are commonly added as reinforcement to enhance the performance of the adhesive properties of Epoxy resin. Due to their excellent stiffness and strength and exceptional high aspect ratio combined with low density, Carbon nanotubes are considered as an ideal candidate for the reinforcement of conventional adhesives. The electrical, thermal and mechanical property of CNT provides a new perspective for improving the conducting performance of the mechanical adhesives.On this study the Epoxy resin was mixed with multiwall carbon nanotubes (MWCNT) as a reinforcement to increase the mechanical, thermal and electrical properties of Epoxy adhesives.(Read more)
