Abstract
The invention relates to the field of composite brake disks formed from fibrous structures. A brake disk according to the invention comprises an annular fibrous structure having two opposing generally planar faces and a binding matrix permeating the annular fibrous structure. Two outer portions are adjacent the planar faces, and an inner portion is disposed between the two outer portions. The two outer portions have lesser tensile strength parallel to the planar faces and greater resistance to wear than the inner portion.
