Abstract

1426416 Carbon disc brake GOODYEAR TIRE & RUBBER CO 28 Feb 1974 [16 Jan 1974] 9120/74 Heading C1A [Also in Division F2] A low wear disc brake includes discs made from carbon-based material having a flexural strength of greater than 5000 p.s.i., an average interlaminar spacing of crystalline and amorphous carbon of not more than 3À39 angstrom units at 15‹ C. and a density greater than 1À40 grams per c.c. The discs may have a thermal conductivity of greater than 0À04 cal. cm./cm.<SP>2</SP>/sec./‹ C. and a friction coefficient of greater than 0À08 between adjacent discs over an operating range of -65‹ to 4000‹ F. The discs may each have an impact strength of greater than 5 inch pounds per inch. The discs may be made by repeated impregnation and heating steps, the final heating step being in excess of 2500‹ C. The discs may be used for forming a low wear disc brake assembly.
