Abstract

This study investigates the impact of exposure to aggressive environments, specifically saline conditions per ASTM B117 standard, on the shear strength of adhesive-bonded joints, crucial for ensuring structural integrity in various industrial applications like automotive, aerospace, and construction. Employing an epoxy-based adhesive to bond AISI304 steel, specimens undergo 14- and 28-day salt spray treatments to simulate harsh working conditions. Torsional shear strength assessment of steel-to-steel adhesive joints is conducted using a torsion test methodology, with an analytical approach used to extrapolate adhesive joint shear strength. This research contributes to understanding adhesively bonded joint performance in challenging environmental conditions, and how the shear strength of the bonded joints changes in relatively small amount of time, offering valuable insights for robust structural designs across industrial sectors.
