A BRIEF LEGENDA
A - COMPOSITE MATERIAL composite materials (also called composition materials or shortened to composites) are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with
characteristics different from the individual components. the individual components remain separate and distinct within the finished structure.
B - MONOLITHIC STRUCTURE the type of construction of traditional surfboard is called monolithic. a monolithic structure is something carved or cast from a single piece of a material. (literally, from the translation of monolith being “one stone”)
C - SANDWICH-STRUCTURED COMPOSITE a sandwich-structured composite is a special class of composite materials that is fabricated by attaching two thin but stiff skins to a lightweight but thick core. the core material is normally low strength material, but its higher thickness provides the sandwich composite with high bending stiffness with overall low density. open and closed-cell-structured foams like polyvinylchloride, polyurethane, polyethylene or polystyrene foams, balsa wood, syntactic foams, and honeycombs are commonly used core materials. open- and closed-cell metal foam can also be used as core materials. laminates of glass or carbon fiber-reinforced thermoplatics or mainly thermoset polymers (unsaturated polyesters, epoxies…) are widely used as skin materials.
