Description
A special class of composite materials that is fabricated by attaching two thin, stiff skins to a lightweight core. The core material is normally of low strength, but its greater thickness provides a sandwich composite that has high bending stiffness but low density. Commonly used core materials include foams (polyethersulfone, polyvinylchloride, Polyurethane, Polyethylene, Polystyrene), balsa wood, gypsum; fiberglass, corrugated sheets, and honeycombs (paper, aluminum, aramid). The skin material may be sheets of paper, cloth, metal, glass, carbon fiber or polymeric. Sandwich panels are used in applications to provide a combination of high structural rigidity and low weight.
