  3. Abstract Strength analysis of glass fiber reinforced composite (GFRC) to aluminum single lap joints becomes crucial when we come to the joining of two dissimilar material like composite and metal. The study compared the performance of single-bolt and double-bolt configurations through experimental testing on a universal testing machine. The results showed that the double-bolted lap joint exhibited higher strength compared to the single-bolt lap joint. This aligns with existing literature, which suggests that additional fasteners can enhance the overall strength and load-bearing capacity of the joint. The project also involved simulating an aluminum-to-aluminum plate joint based on a research paper, providing a foundation for further investigations in the field of composite-to-metal joining.

  5. Literature Review • Title: An Investigation of the Tensile Strength of a Composite-To-Metal Adhesive Joint. • Abstract The current study focuses on the investigation of overlap strength and surface preparation of steel adherent joint of steel to composite butt joint.The composite used in the study was unidirectional glass/epoxy composite.Both numerical and experimental study was carried out to validate the results. The results obtained was in the form of axial elongation and strains at various locations. The results revealed that surface preparation does not play a significant role in the joint strength. Further, the strength was compared with the previously published results of similar investigations and they appeared promising even better for some of the samples/experiments.

  6. Literature Review • Title: Mechanical Joining of Fibre Reinforced Polymer Composites to Metals—A Review. Part I: Bolted Joining • Abstract Multi-materials of metal-polymer and metal-composite hybrid structures (MMHSs) in transportation industries represents a pivotal opportunity to reduce the product’s weight without compromising structural performance. challenge for manufacturing MMHSs lies in the lack of robust joining solutions. Conventional joining processes, e.g., mechanical fastening and adhesive bonding involve several issues.

  7. Literature Review • Title: Effect of surface treatment on the performance of composite-composite and composite-metal adhesive joints • Abstract The use of Fiber-Reinforced Polymer Composites (FRPCs) in automotive, aerospace, and naval applications has increased significantly due to the requirement for a high performance-to-weight ratio. One the issue in using composite parts is their joining to the metal parts in the global structure. Though the effect of physical surface treatments on the performance of joints has been reported in the literature, however, the effect of chemical surface treatment of composites on the mechanical performance of adhesive joints was rarely studied. In this article, the effect of chemical treatment (alkaline permanganate), of the composite surfaces on the single lap shear strength and Izod impact strength of composite-composite and composite-metal adhesive joints is reported. The results showed that the chemically treated joints demonstrate a significant improvement in these properties. Peel ply treatment is a quite simple way to get a suitable surface; it consists in a single ply placed on one side of the composite material prior to the manufacturing process. During the cure cycle, this ply is progressively impregnated with the polymer matrix of the composite.

  8. Literature Review • Title: Damage analysis of composite–aluminium adhesively-bonded single-lapjoints. • Abstract This study explores how we can stick together aluminum and carbon–epoxy composites using glue for making strong structures. We tested different glues and how much the materials overlap. Using computer simulations and real experiments, we found that the type of glue really matters. A special computer method helped us predict how strong the glued parts would be and gave us a quick way to design structures. The strength of the joints depended on the glue used, and we discovered that certain glues worked better than others. This information can help design better structures by choosing the right glue and how the parts fit together.

  28. Conclusion  The study found that the efficiency of the double-bolted lap joint is more than twice that of the single lap joint. The simulation of the aluminum-to-aluminum joint provides a solid foundation for the project's simulation work. These findings suggest the double-bolted lap joint is a superior design choice for the application.
