アルミニウム合金と炭素繊維強化樹脂の摩擦撹拌点接合とそのウェルドボンド

In this study, the possibility of using adhesive for friction stir spot welding was investigated with the aim of improving the strength and rigidity of aluminum and CFRP dissimilar material joining members and improving galvanic corrosion resistance. As a result, it was found that there is a trade-off relationship between the friction stir spot welding, which improves the joint strength in proportion to the frictional heat, and the weld bond, in which the adhesive is thermally decomposed by the frictional heat. When using adhesive together, it is necessary to consider the selection of adhesive and the optimization of frictional heat according to the application and required strength level.
