PROBLEM TO BE SOLVED: To obtain a reinforced vitreous carbon composite suitable for use in formation of wear-resistant assemblies such as joint prosthetic devices, bearings, electric current collectors, sealing components, brake linings, electric motor brushes and other tribological products. SOLUTION: This reinforced composite 10 comprises a base member 14 having a main body of a reinforced vitreous carbon 12. The composite is formed by impregnating a metal-reinforced structure with a furfuryl alcohol resin, polymerizing the resin while thermally controlling the polymerization process and producing a continuous phase of an isotropic, homogeneous and substantially completely void-free poly(furfuryl) alcohol in a bulk composite having >25 mm size in, e.g. each of the x-, y- and z-directions thereof. |
