| Popis: | Through an experimental study, this paper describes the behavior of single-lap bonded and bolted–bonded connections for configurations with minimum geometric parameters proposed in design references. Two types of multi-material connections are considered: glass fiber reinforced polymer (GFRP)–steel and aluminum–steel. At first, the behavior of bonded connections using methacrylate and epoxy adhesives is evaluated. Then, the contribution of adhesive in bolted connections is investigated. Test results show that on bonded joints, failures mostly occur at the substrate to adhesive interface. Sanding the GFRP plate was found to improve the connection strength. Despite their lower elastic modulus, methacrylate adhesives with larger capacity to undergo plastic deformation provide better strength than other methacrylate and epoxy adhesives. For bolted–bonded joints, the adhesive was found to improve the elastic behavior and the strength of GFRP–steel joints while its effect for aluminum–steel joints was not apparent due to reduced bonded surface and the high strength performance of the bolted plates. |
