Abstract
This study introduces a new nano-adhesive which is an improvement over the conventional epoxy resin that is widely used in the automobile industry. Multi-walled carbon nanotubes (CNTs) (1% to 4% by weight) were mixed into the epoxy resin by using a mixer. The bubbles generated during mixing were removed by using a high vacuum. The electrical and mechanical properties of the joints were assessed by considering the geometric parameters of the nano-adhesive bonded joints to optimize quality and performance for actual application. The results show that the electrical resistance of nano-adhesives decreased with increased CNT weight percentage and decreased thickness of the bonded layer. Static tensile strength increased dramatically at a CNT weight percentage of 2% compared with other values. The surface treatment condition of the plates also affected the tensile strength of the nano-adhesive bonded joints.
