Honeycomb is typically used as a core material in sandwich constructions whereby it is sandwiched between strong facing skins such as aluminum, steel, wood, paper and fiberglass. The resulting construction behaves much like an I-beam, which benefits from increased strength and stiffness at reduced weight.
Made up of cell structures that are round rather than hexagonal, more closely resembling honeycomb structures that exist in nature. Polypropylene honeycomb properties are more uniform in all directions across the entire sheet of honeycomb.
