Foams
Foams are widely used as internal structure in realizations of composite manufactured goods where required maximum structural performance with minimal resin absorption, thus ensuring a significant reduction of the final weight. They are particularly suitable for sandwich constructions in different areas, such as marine, renewable energies, automotive, modeling, for the production of equipment and tools for leisure activities and in many other fields; this type of core is composed by a rigid but thermoformable structure, then it can be molded consecutively and simultaneously to the laminate, both in flat structures, both in structures with not too complex forms, speeding up the production process.
