Abstract
The limited metal-polymer interlaminar property is a significant obstacle to the advancement of Ti/Carbon Fiber (CF)/Polyether Ether Ketone (PEEK) hybrid laminates. We report for the first time a novel method by utilizing the mussel-inspired Polydopamine (PDA) to introduce a strong chemical-physical bonding between titanium and PEEK. The enhanced Fiber-Metal Laminate (FML) exhibits a significant 48.82% enhancement in Interlaminar Shear Strength (ILSS). In addition, it alters the failure mode of the FML from single metal-resin interlaminar delamination to a multi-mechanism, including debonding, delamination of different composite layers, leading to a 28.57% improvement in maximum displacement.
