Abstract

In this study, the magnesium alloy sheet was treated by laser ablation to develop a type of conversion film on magnesium alloy aimed for simultaneous improvement in interlaminar strength and galvanic corrosion resistance of CFRP/Mg laminates. The results show that laser ablation can effectively enhance the Mode I (peel) interlaminar strength of CFRP/Mg laminates due to the formation of chaotic structure on the magnesium surface, and the peel strength decreases with the increase of scan speed. In addition, the laser ablation layer can provide an excellent protection against the galvanic corrosion in CFRP/Mg laminates, since the isolation between carbon fibre and magnesium substrate can be obtained by laser ablation.
