Light Weight Applications of Sandwich Panels in Various Industries
Abstract: Sandwich construction is of particular interest and widely used, because the concept is very suitable and amenable to the development of lightweight structures with high in-plane and flexural stiffness. Sandwich panels consist typically of two thin face sheets (or facings, or skins) and a lightweight thicker core. Commonly used materials for facings are composite laminates and metals, while cores are made of metallic and nonmetallic honeycombs, cellular foams, balsa wood …
