We present a novel approach for designing lightweight sandwich structures by using an assembly of topologically interlocked building blocks as a core of the sandwich. The results of a study in three point bending tests demonstrate a significant increase in maximum deflection before failure and absorbed energy over that of a sandwich with a monolithic core.
