A dual-function supercapacitor carbon fiber composite stores electrical energy and functions, for example, as the body shell of electric vehicles (EVs). This is achieved with a vertically aligned graphene on carbon fiber electrode, upon which metal oxides were deposited to obtain ultra-high energy density anode and cathode. A high-strength multilayer carbon composite assembly is fabricated using an alternate layer patterning configuration of epoxy and polyacrylamide gel electrolyte. The energized composite delivers a high areal energy density of 0.31 mWh cm.sup.−2 at 0.3 mm thickness and showed a high tensile strength of 518 MPa, bending strength of 477 MPa, and impact strength 2666 J/m. To show application in EVs, a toy car body fabricated with energized composite operates using the energy stored inside the frame. Moreover, when integrated with a solar cell, this composite powered an IoT (interne of things) device, showing feasibility in communication satellites.

A component of a motor vehicle, which is reinforced in at least one region subject to tensile loading by at least one stiffening tape having fibers embedded in plastic. This should make it possible to achieve local and weight-optimized stiffening.
