EFFECT OF RIVETING ON THE JOINT STRENGTH OF ADHESIVELY BONDED DOUBLE LAP JOINTS

The scope of this study, is to determine the effectiveness of using rivets in the adhesive joints in order to combine plastic based composite materials which are often used in today's engineering structures, to the joint strength. For this purpose, double lap joints are prepared in 3 different types of configuration included adhesive, pinned and both adhesive and pinned and also prepared in 3 different overlap lengths as 30, 45 and 60 mm. Stress-strain diagrams were derived by exposing the joints obtained, to the axial tensile test and then the most appropriate joint type was determined by comparing each of the results obtained. The evaluation of the results pointed out that the hybrid joints where adhesive and rivet are used together, can carry much more load than the joints where only adhesive was used or the joints which are combined with rivet in terms of joint strength.
