This study investigates the enhancement of mechanically bolted joint efficiency in composite laminates by incorporating a metal interlayer. Specifically, a 0.2mm thick perforated and sandblast-finished SAE 1086 steel sheet was utilized as the metal interlayer, which was colaminated with Style 1581 glass cloth and Ciba Geigy LY 556 epoxy resin to form the laminate. The research focused on understanding the effects of varying the volume fraction of the metal shim on bearing strength, determining the minimum width-to-hole diameter (W/D) and end distance-to-hole diameter (e/D) ratios required to achieve full bearing strength, and assessing the impact of the steel shim on failure modes. Through experimental testing, a data basis was developed to provide insights and increase reliance on the application of steel interlayered reinforcements. The findings highlight the advantages of incorporating high-strength metal shims to mitigate local stress concentration, ultimately improving the overall efficiency of mechanical joints in composite structures. This research addresses the substantial challenges faced in achieving high joint efficiency in traditional mechanical joints and offers a potential pathway to optimize joint design in advanced composite materials.
