Abstract

In this paper, a galvanic corrosion-resistant carbon fiber metal laminate (CARALL) is developed. Aluminum alloy 2024-T3 is selected as the metal layer. A surface treatment technique combining a sulfuric acid anodizing with a hybrid sol-gel coating for the aluminum alloy is developed to prevent CARALL from galvanic corroding. Electrochemistry tests are conducted to evaluate the properties of electrochemistry of aluminum alloy treated by the present method. The test results prove that the combination of sulfuric acid anodizing and hybrid sol-gel coating can provide good protection against the galvanic corrosion in CARALL. Moreover, aluminum alloy sheets and carbon fiber/epoxy prepreg are stacked and cured in an autoclave to fabricate CARALL. The cross-section of fabricated CARALL is investigated by scanning electron microscope (SEM) and electron probe micro analyzer (EPMA). Well bonded thin interlayer consisting of composite layers is formed between aluminum alloy and carbon fiber-reinforced epoxy layer. Corrosion tests of CARALL and aluminum alloy are conducted, the present CARALL shown excellent corrosion resistance. Three-point and fivepoint bend tests are conducted to evaluate the interlaminar shear strength of the CARALL.
