In this paper, the main attention is focused on the galvanic corrosion problem of carbon fiber metal laminate (CARALL). A galvanic corrosion resistant CARALL is developed based on nanocomposite coating. CARALL is composed of CFRP layers and aluminum alloy layers. T300/#2580 prepreg is used as CFRP layer. Aluminum alloy sheet of 2024-T3 is selected as the metal layer. Nanocomposite coating consists of a sulfuric acid anodizing and a silica nano-particle reinforced hybrid sol-gel coating, and the composite coating is conducted on the surface of 2024-T3 to prevent the galvanic corrosion between carbon fiber and aluminum alloy. Effect of silica nano-particles on the properties of corrosion resistance is investigated by electrochemical tests. The cross-section of fabricated CARALL is investigated by scanning electron microscope (SEM) and electron probe micro analyzer (EPMA). Corrosion and mechanical tests are also conducted. Good corrosion resistance and proper interlaminar shear strength for CARALL are obtained.
