Effect of Anodizing Process on Inter Laminar Shear Strength of GLARE Composite through T-Peel Test: Experimental and Numerical Approach

Abstract

Glass laminate aluminum reinforced epoxy (GLARE) is a vital class fiber metal laminates (FMLs) and advanced aircraft material. Despite the ongoing research and utilization of FMLs in applications like structures and aircraft, the weakness is particularly the materials’ delamination. This phenomenon is still observed as the primary confinement for an increased and efficient utilization of the materials. In this study, interlaminar shear strength (ILSS) of GLARE composite is improved through many chemical treatments and the anodizing process. T-peel test characterizes the ILSS through the ASTM D1876–08 standard. The numerical model was also developed to predict the ILSS of GLARE laminates and their performance. Results show that the anodizing process enhances the ILSS of GLARE composite. Anodizing makes the aluminium surface porous and improves glass fiber's adhesion with Aluminum surface. The numerical models successfully predict experimental results for un-anodized samples.
