Abstract: A method for synthesizing carbon nanowires directly on glass fibers or carbon fibers is provided to obtain a nanocomposite having excellent strength, elasticity and tensile property derived from glass fibers or carbon fibers, and to realize increased adhesion between a functional polymer and the nanocomposite when producing a reinforced composite. A method for synthesizing carbon nanowires such as carbon nanotubes or carbon nanofibers directly on glass fibers or carbon fibers as a support comprises the steps of: coating metal the surface of the glass fiber support or carbon fiber support with metal catalyst particles; and synthesizing carbonaceous nanowires such as carbon nanofibers or carbon nanotubes directly on the surface of the glass fiber support or carbon fiber support by way of the coated support with no dispersion step to obtain a nanocomposite. The carbon nanofibers or carbon nanotubes are controlled to a desired growth distribution density or shape by adjusting at least one factor selected from concentration, coating process, production temperature and time.
