    Abstract: A molecularly resilient and high-energy transferable material and method of reinforcing and strengthening substrates with the same. The material includes aliphatic polyurea moieties coated on the surface of a pre-curing or curing epoxy, that may or may not compose a fiber reinforced epoxy (F/E) layer, constituting an isophorone diisocyanate amine (IDA) epoxy-surface modification (reaction) to form an interfacial epoxy-polyurea hybridized-matrix (IEPM) material between the epoxy (that may reside on an F/E layer) and a cured polyurea layer. Through its unique set of molecular vibrational properties, which are designed into the IEPM by controlling the thermodynamic IPA reaction, the chemically bonded and molecularly resilient (regenerative) IEPM material incorporates significant fracture toughness, loss modulus (material damping), and reduced elastic modulus into structural substrates and high-tenacity fibers to which it is adhered.
