The objective of this study is to find a better joint configuration which has more strength with minimum added weight. Hybrid joining is the principle of combining different joining technologies. Here, Mechanical fastener and adhesive are used together. Use of a mechanical fastener in hybrid joint is a fail-safe design, but it is an added weight to the structure. Because fastener did not contribute to tensile strength until the adhesive fails. Hence attachments are used to alternate the load paths to the fastener and utilizing the fastener to provide strength to the joint once the joint was loaded. Numerical analysis is carried out to optimize the added curve attachment on conventional hybrid lap joint. Hybrid lap joint with curve attachments of different load transfer angles are designed and analyzed to find a better joint configuration. The analysis results shows that the hybrid joint with the curve attachment of load transfer distance to height ratio of 4 (14 degree) provides the maximum load transfer to the fastener and has the higher strength than other lap joint configurations.
