Modeling and Experimental Validation of CFRP-Metal Joints Utilizing 3D Additively Manufactured Anchors

Abstract The joining techniques between carbon fiber reinforced polymer (CFRP) and metal are of great importance in many areas structural mechanics where the optimization weight, rigidity, strength is a necessity (such as aeronautics, vehicles, energy generation, biomechanics). As result, several types metal-composite joints have been manufactured using different methods, with 3D anchor solution attracting significant attention. This study evaluates geometries applied to single lap through preliminary finite element method (FEM) simulations experimental validation on CFRP Inconel 625 produced via laser beam powder bed fusion (LB-PBF) additive process. models proposed increase complexity. homogenization process employed determine equivalent properties joint region that occupied by anchors CFRP. model also supports topology parametrization assess impact geometry properties. provides under tensile load for various anchoring surface topologies.
