Abstract
Modular, energy-dissipating material prevents failure of adhesives, fibers and composite and other structures. The modules comprise folded subunits or domains that unfold in a stepped fashion at forces below that necessary to break the backbone of the material and, with adhesive material, below that necessary to break the bonds that fasten the material to surfaces being glued.
