The most interesting and promising ways to obtain composite material consisting of polymeric resins and fiber-glass structures are hybrid sandwich structures. The faces of the sandwich structure can be metallic materials (such as aluminum alloys or stainless-steel) and non-metallic materials (polymeric laminates with glass-fiber or carbon-fiber). For special applications in the field of aircrafts or shipbuilding, where the main priority is the strength/weight ratio, honeycomb core sandwich materials are used. In these materials, the core can be made of paper that's pre- impregnated with resin and especially of aluminum alloys or polymers reinforced with glass-fibers.
