applicability of adhesive embossing Hybrid Joining process to glass fiber reinforced plastic and metallic thin sheets
Journal of Materials Processing Technology, 2014Co-Authors: Zhequn Huang, Sumio Sugiyama, Jun YanagimotoAbstract:Abstract Adhesive–embossing Hybrid Joining process was applied to A2017P and three types of glass-fiber-reinforced plastic (GFRP) thin sheets. Optical microscopy shows that a sound A2017P–thermosetting GFRP Hybrid joint without crack/delamination in the composite or adhesive failure can be produced by optimizing adhesive thickness, embossing stroke and embossing temperature. The results of tensile shear test indicate that the optimally Hybrid-bonded A2017P–GFRP joint exhibits improved load carrying capability, slip displacement and better energy absorbing characteristics than the adhesively bonded joint when subjected to tensile loading. This investigation shows that the adhesive–embossing Hybrid Joining process is a competitive alternative Joining method for the fabrication of ultra lightweight thermosetting GFRP-metal Hybrid structures and has great potential for wider applications, which is attributed to its benefits in terms of Joining properties, operation simplicity, weight-cost effectiveness and recyclability.

adhesive embossing Hybrid Joining process to fiber reinforced thermosetting plastic and metallic thin sheets
Procedia Engineering, 2014Co-Authors: Zhequn Huang, Sumio Sugiyama, Jun YanagimotoAbstract:Abstract Aiming at increasing weight-to-strength structural performance and reducing fabrication cost, fiber-reinforced thermosetting plastics (FRPs) should be joined to other lightweight metals. However, reducing the thicknesses of components for lightweight products makes FRP-to-metal Joining a greater challenge. In this study, warm embossing process was applied to improve the single-lap adhesive bonding quality for thermosetting FRP and A2017P-T3 thin sheets. The use of a dummy sheet, the relative position of the sample and dummy sheet and the embossing parameters were investigated. The effects of the types of fiber and polymeric matrix as well as the ply laminates on the feasibility of the Hybrid Joining were also clarified. This study shows that adhesive–embossing Hybrid Joining process which exhibits remarkable superiorities in terms of tensile shear load, displacement and absorption energy is a competitive Joining method for ultra lightweight thermosetting FRP-metal Hybrid structures.

Hybrid Joining process for carbon fiber reinforced thermosetting plastic and metallic thin sheets by chemical bonding and plastic deformation
Journal of Materials Processing Technology, 2013Co-Authors: Zhequn Huang, Sumio Sugiyama, Jun YanagimotoAbstract:Abstract A new Joining process for thin metallic and continuous carbon fiber reinforced thermosetting plastic (CFRP) sheets is proposed. This Joining process is a Hybrid of chemical bonding and plastic deformation, usable for ultra-lightweight structures. In contrast to conventional Joining methods, such as rivet Joining with an adhesive, the proposed method does not require any additional components and can eliminate holes that would cut the continuous carbon fibers and cause stress concentration. Hence, a smaller weight and a higher Joining quality can be attained, especially for thin sheets. Aiming at making comparison and demonstrating the applicability of the proposed Hybrid Joining method, two thermosetting CFRP sheets with different laminates were used as lap adherends in the experiment. The effects of the deformation temperature, the use of a dummy sheet and the relative positions of the sample and dummy sheet on the Joining quality were systematically investigated and optimized. The optimal Hybrid joint shows high-quality bonding without delamination or adhesive failure. The tensile shear test of single-lap A2017P-CFRP Hybrid joints manufactured under optimal experimental conditions indicates that, compared with adhesive bonding and conventional rivet Joining with an adhesive, the proposed Joining method has obvious superiority in terms of tensile shear load, slip displacement and absorption energy.

a Hybrid Joining technology for aluminum zinc coated steels in vehicles
Journal of Materials Science & Technology, 2010Co-Authors: Cheolwoong Choi, D C Kim, Daegeun Nam, Yangdo Kim, Yeongdo ParkAbstract:Currently, in the automotive industry, Joining of the aluminum alloys with the steel is a crucial problem to be solved. Conventional Joining techniques including resistance spot and gas metal arc welding are not acceptable for those applications due to a number of metallurgical problems. The investigation was carried out to develop the Hybrid Joining process combining the resistance spot welding and brazing. In this study, an attempt was made to apply Hybrid process to the Joining of dissimilar sheet metals, Al-Mg-Si (6000 series) alloy and low carbon steel sheet. Hybrid process (resistance spot weld/brazing) using filler metal was found to be effective to overcome the incompatibility between aluminum alloy and steel. Although Hybrid Joining process of Al alloy sheet and steel sheet did not produce acceptable bond strength, it was proved to have reasonable interfacial bond layer if the optimal process condition was applied.

Combining resistance spot welding and friction element welding for dissimilar Joining of aluminum to high strength steels
Journal of Materials Processing Technology, 2019Co-Authors: João Pedro Oliveira, Tim Abke, K. Ponder, E. Brizes, P. Edwards, Antonio J. RamirezAbstract:Abstract A multi-process Joining technique that combined resistance spot welding and friction element welding was used to produce a three-sheet multi-stack of advanced high strength steel and precipitation hardened aluminum. Each weld process was tested independently and as a combination to better understand how multi-step welding affects joint performance. Weld interfaces and surrounding heat affected zones were investigated using microstructural and mechanical techniques, including scanning electron microscopy and nanoindentation. All tests indicated that excellent strength was maintained above the maximum breaking force threshold regardless of offset distance between the friction element weld and the center of the resistance spot weld nugget. A change in fracture mode was observed with interfacial fracture occurring at offset distances below 7 mm and nugget pull out or partial thickness failure occurred at offset distances above 7 mm. The present study indicates that Hybrid Joining techniques have minimal effect on both the mechanical and microstructural weld properties and allow for new dissimilar metal weld designs to be implemented in the automotive industry.
