ABSTRACT:
A wear-resistant composite structure which is especially suitable for use in the formation of sealing components, brake linings, electrical motor brushes, bearings, and like products, is disclosed. This composite structure includes as its primary component vitreous carbon in a continuous phase, and strengthening fibers interspersed throughout the vitreous carbon in a discontinuous phase. These fibers are individually convoluted in configuration, so as to improve the crack-resistance and other physical properties of the vitreous carbon. A suitable method of forming such wear-resistant composite structure is also disclosed.
