Abstract EN
Carbon fiber-reinforced plastics- (CFRP-) steel single lap joints with regard to tensile loading with two levels of adhesives and four levels of overlap lengths were experimentally analyzed and numerically simulated.
Both joint strength and failure mechanism were found to be highly dependent on adhesive type and overlap length.
Joints with 7779 structural adhesive were more ductile and produced about 2-3 kN higher failure load than MA830 structural adhesive.
Failure load with the two adhesives increased about 147 N and 176 N, respectively, with increasing 1 mm of the overlap length.
Cohesion failure was observed in both types of adhesive joints.
As the overlap length increased, interface failure appeared solely on the edge of the overlap in 7779 adhesive joints.
Finite element analysis (FEA) results revealed that peel and shear stress distributions were nonuniform, which were less severe as overlap length increased.
Severe stress concentration was observed on the overlap edge, and shear failure of the adhesive was the main reason for the adhesive failure.
