Abstract

See full text

A flexible multi-material structure comprises a spring skeleton comprising a plurality of repeating cells, the cells filled with an infill material, wherein the spring skeleton is one of a machined spring structure and a wave spring structure. The spring skeleton may comprise one of steel and polycarbonate blends, and the infill material may consist of one or more of foamed and monolithic elastomers. The foamed and monolithic elastomers consist of one or more of silicones, polyether, and polyurethane. The Poisson ratio of the infill material is about 0.1 to 0.3. The repeating cells of the spring skeleton have a predetermined wall thickness (t), wall height (h), and revolution symmetry.
