Abstract
A plurality of closed structural metal cells are joined into an aggregate arrangement to form a composite material. Each cell encapsulates a fluid or fluid-like filler therein to provide controllable strength and shock-absorbing characteristics to the material. The resulting closed cell metal composite finds many advantageous uses including use as a prosthetic device, a casting, or an automotive component. The component material is elastically compliant or stiff, depending on the design, as well as lightweight and crush resistant. The material provides desirable physical properties such as thermal and electrical conductivity and shock-absorbing characteristics.
