Effect of anodizing process on the mechanical properties of glass fiber reinforced aluminum laminates

The influence of varying anodizing voltage and time on the tensile strength and interlaminar shear strength(ILSS) of glass fiber reinforced aluminum (GLARE) laminates was investigated. The topographic information of Al₂O₃ anodic film and fracture surface on laminates was obtained by SEM. The effect of aluminum/resin adhesion on the mechanical properties of GLARE laminates was discussed. The results show that tensile strength and interlaminar shear strength of laminates increase with prolonging the time of anodizing at 20 V, and reach maximum at 20 min, then decrease with extending the anodic time. The tensile strength and interlaminar shear strength of laminates increase with raising the voltage of anodizing at 20 min, and reach maximum at 20 V, then decline with increasing the anodic voltage.
