▎ 摘　　要

NOVELTY - The fiber composite (100a) has a metal layer (20) formed on a surface of a conductive fiber bundle (10). The surface of the metal layer is coated with graphene. Surfaces of conductive fiber strands (1) are coated with the metal layer. The conductive fiber strands are formed of fibers by gathering a set of carbon nanotube strands, where diameter of the carbon nanotube strands is for about 1 nm to 10 nm. A metal particle is located between the conductive fiber strands. USE - Fiber composite. ADVANTAGE - The fiber composite has effect of the fiber composite having better electrical and mechanical properties occurs, thus improving performance of the fiber composite. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for producing a fiber composite. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the fiber composite.
