Abstract: A spring having a sandwich-structured composite including a core structure, a top skin, and a bottom skin. The core structure comprises a framework, or array of geometric shapes designed to absorb and distribute the forces applied to the spring. Preferably the framework comprises an array of hexagonal columns that extend between the top and bottom skins. The top and bottom skins are laminated to a respective top and bottom surface on the core structure. The spring can comprise any suitable type of spring that is well-known in the art, including a leaf spring, a coil spring (or helical spring), a torsion spring (or clock spring), a conical spring, and so forth.
