WebbComposite sandwich structures are special types of composite materials that are produced by inserting a thick, lightweight core between two thin, stiff and strong polymer composite facesheets. Also, an adhesive material is used to join the facesheet to the core. WebbKeywords: Sandwich structure, corrugated-core, honeycomb, foam core.
