Abstract: A brake disk frictional module is provided, composed of sintered metallic material reinforced throughout its entire volume by a grid system of pure metal or metallic alloy. The friction module may be manufactured by sintering the metallic material with the grid reinforcement in either a mold or within the brake disk cup. The internal reinforcement of the frictional module prevents spalling weight loss, friction coefficient decay, or other physical defect as caused by frictional strain during use. The reinforcement material reduces the overall temperature of the disk during use, and aids frictional coefficient of the disk because of the metallic compatibility of the metallic material and grid system.
