Abstract
A composition comprising polymer-bound fiber tows containing carbon fibers, the polymer-bound fiber tows having an average length of 3 mm to 50 mm measured in the fiber direction, and an average bundle thickness of 0.1 mm to 10 mm measured perpendicular to the fiber direction, and in which at least 75% of all polymer-bound fiber tows have a length that is at least 90% and not greater than 110% of the average length combined with a carbon-ceramic material.
