Classification of fiber metal laminates (FMLs), adhesion theories and methods for improving interfacial adhesion: A review

Abstract

Fiber metal laminates (FMLs) have the advantages of both metals and composite materials, making them highly promising materials in the aviation industry. The metal-polymer interfacial adhesion has an extremely important impact on the overall performance of FMLs. The present review provides a comprehensive review on the classification of FMLs, interfacial adhesion theories and methods for improving metal-polymer interfacial adhesion. First, the development history of FMLs is briefly reviewed and different types of FMLs are discussed in detail in terms of metal, reinforcement and matrix. Then, several currently known interfacial adhesion theories are elaborated. Finally, a comprehensive discussion on methods of surface treatment and nanoparticle addition is presented for improving metal-polymer interfacial adhesion.
