This allows the material to behave much as a simple metal structure, but with considerable specific advantages regarding properties such as metal fatigue, impact, corrosion resistance, fire resistance, weight savings, and specialized strength properties.
During the past decades, increasing demand in aircraft industry for high-performance, lightweight structures have stimulated a strong trend towards the development of refined models for fiber metal laminates (FMLs).
The most well known FMLs are: Taking advantage of the hybrid nature from their two key constituents: metals (mostly aluminum) and fiber-reinforced laminate, these composites offer several advantages such as better damage tolerance to fatigue crack growth and impact damage especially for aircraft applications.
Metallic layers and fiber reinforced laminate can be bonded by classical techniques, i.e. mechanically and adhesively.
Examples of FMLs include aramid fibers, GLARE, and basalt aluminum infusion (B.Al.i).
