Abstract

Abstract: The current work investigates the influences of different surface modifications on the flexural characteristics of carbon fiber reinforced aluminum (AA2024-T3) laminates fabricated at 3/2 sequence. Among all types of surface modifications, mechanical abrasion by 220-grit paper shows highest flexural strength. The flexural load of Al/0°/Al/0°/Al configuration is about 19% higher in comparison with mechanical abrasion (220-grit paper) with chemical treatment due to higher interfacial strength. However, corrosion resistance is improved about 30 times in the later modification. In-situ imaging reveals that failure of Al/0°/Al/0°/Al laminates initiates by micro-buckling of carbon fiber whereas matrix cracking initiates the failure in Al/90°/Al/90°/Al laminates.
