Patent number: 5895716Abstract: This invention relates to carbon--carbon (C--C) composite comprising carbon fibers or carbon fabric, carbon char on the carbon fiber or fabric and pyrolytic carbon on the carbon char, wherein the density of the carbon composite is at least 1.3 g/cc. The invention also relates to wet friction elements and power transmission devises containing the same. The invention also relates to methods of preparing the carbon--carbon (C--C) composites. These C--C composites and wet friction elements and power transmission devises made therefrom have improved friction properties desired by wet brakes and clutches. These C--C composites provide improvements in cost, and when run against metals, such as steel or iron, improvements in wear and frictional behavior compared to known C--C composites for wet friction applications. In one aspect, the carbon--carbon does not require bonding to a metal backing or core material.Type: GrantFiled: January 19, 1996Date of Patent: April 20, 1999Assignee: The B.F.
