FML; the logical Aluminium replacement Aluminium remains a preferred shipbuilding material. Unfortunately it also has some minor downsides like the material's softness. At this moment I'm studying on the development of Fiber Metal Laminates (FML's) developed by Stork. For those not familiar with FML's, they are a composites made of thin metal layers (Alu or stainless steel foil) and a fiber reinforced matrix. The test are very impressive. Both the lightness of the materials and the enormous strengths are remarkable. FML's are widely used in the aviation industry. The Airbus A380 is built with an FML called glare. FML's are likely to be introduced in yachting in applications like floors, doors, hatches and inner walls. At this point it will probably take at least 3 years to make a yacht hull in FML. The formability is limited and complex, but the engineers will find a solution for that.
