Foam Core refers to a lightweight cellular core material used in composite sandwich structures to provide thickness, stiffness, and load distribution without significantly increasing weight. In structural applications, Foam Core works in conjunction with high-strength face sheets such as FRP, aluminum, or steel to form a sandwich panel that achieves an exceptional strength-to-weight ratio. The fundamental role of Foam Core is to resist shear forces, stabilize face sheets, and improve bending stiffness. Compared to solid materials, structural Foam Core enables engineers to design larger, lighter, and more energy-efficient structures. Due to its closed-cell structure, Foam Core also offers thermal insulation, moisture resistance, and vibration damping. These combined properties make Foam Core indispensable in industries such as construction, marine, transportation, wind energy, and modular buildings, where lightweight structural performance and durability are critical.
