Abstract
Friction disk rings and a method for near net-shape fabrication of the friction disk rings are disclosed. The method includes cutting a friction material into tiled trapeziform strips. The strips are then folded into a disk ring structure that can be hot-pressed, stitched, or sewed, to preserve the disk ring structure. The disk rings include multiple layers of a friction material, each layer includes a plurality of triangular shaped panels. In one embodiment, the triangular shaped panels are symmetric with respect to the radial center of the disk ring.
