Sandwich core materials can be used in many different applications

Composite materials are made from two or more constituent materials with significantly different physical or chemical properties, that when combined, form an overall structure with characteristics different from the individual components.

The basic idea is simple; the execution is a bit more advanced. Two thin, strong and stiff skins, of fiber reinforced plastics or solid material, are attached to a lightweight core by press-bonding or lamination. The result is a component with a very high stiffness-to-weight and high bending strength-to-weight ratio. A variety of core materials is used to give the final product additional desired features, such as FST resistance or insulation.
