Abstract

A three-dimensional (3-D) composite structure includes a 3-D lattice structure (32) having a plurality of electrically insulative struts, a matrix phase (38) surrounding the 3-D lattice structure (32), first and second electrically conductive face sheets (34, 35) positioned on two faces of the 3-D lattice structure (32), and a plurality of electrically insulative containment sheets positioned on all faces of the 3-D lattice structure (32) that do not include the first and second face sheets (34, 35). The matrix phase (38) includes an electrorheological material. The first and second face sheets (34, 35) are positioned such that an electric potential applied between the first and second face sheets (34, 35) creates an electric field in the matrix phase (38) that causes a desired reversible alteration to the viscosity of the matrix phase (38). The first and second face sheets (34, 35) and the plurality of containment sheets are collectively configured to contain the matrix phase (38) within the 3-D lattice structure (32).
