2326 Deformation and strength of adhesive-mechanical fastening hybrid joints
Details
Recently materials for car structures are gradually changing from steels to lighter ones such as aluminium alloys, polymer alloys and composite materials. To join such dissimilar materials, adhesively bonded joints are most promising. Mechanical fasteners including bolts or rivets are also used together with adhesives as hybrid joints in some cases. In this research, single lap joints of aluminium, Carbon Fiber Reinforced Plastics and steel adherends bonded with adhesives were used as specimens. Aluminium rivets and steel bolts are applied to the joints. As results of the research, it is found that applying rivets is not effective to increase the maximum load, and applying bolts is effective for not only the strength but also the absorbed energy.
