A new and useful structure and method for reinforcing a structural member is provided. A fabric cover on a selected portion of the structural member; wherein (a) the fabric cover comprises a plurality of different carbon fiber types in a predetermined configuration, (b) each of the different carbon fiber types has a different modulus of elasticity than the other carbon fiber types, and each of the different carbon fiber types being of a type and in an orientation such that it will carry at least a part of an impact load due to pressure wave impact, inertia loading due to ground motion forces, and combinations of the foregoing, and (c) the predetermined configuration and the different modulus of elasticity of the different carbon fiber types designed to react to energy from forces due to pressure wave impacts, inertia loading due to ground motion forces, and combinations of the foregoing, in a manner such that higher modulus carbon fiber types will fracture before lower modulus carbon fiber types, so that in dissipating the energy of the impact load when the higher modulus carbon fibers break, the lower modulus carbon fiber types.
