Structural Foam Core is a category of Foam Core specifically engineered to carry mechanical loads within composite sandwich structures. Unlike insulation-only foams, structural Foam Core exhibits defined compressive strength, shear strength, and shear modulus values that can be used in engineering calculations. These properties enable the Foam Core to transfer loads between face sheets, prevent buckling, and maintain panel integrity under bending and impact. Structural Foam Core materials are typically used in load-bearing panels, floors, walls, decks, and shells. Manufacturers design structural Foam Core with controlled density, uniform cell structure, and consistent mechanical performance to ensure reliability. In many industries, structural Foam Core is considered an engineered material rather than a commodity foam, requiring strict quality control and performance validation.
