Failure analysis of fiber reinforced adhesively single lap joints

In this study; experimental failure analysis was investigated on adhesively single-lap joints produced using adhesives reinforced with glass fibers and carbon fibers. Epoxy adhesive impregnated fiber was used to join composite plates with single-lap joints. It is aimed to strengthen the joint by using fiber layers impregnated with adhesive between the two composite plates. The failure loads of the joints obtained with reinforced adhesives were compared with the failure loads of the joints attached to the non-reinforced adhesive. Also, 0o, 15o 30o and 45o fiber reinforcement angles were used to investigate the effect of fiber reinforcement angle. As a result of the experimental study, it was determined that reinforcing the adhesives can increase the damage loads by up to 31%.
