A disk damping core comprising: a first disk leaf having at least one first sloped contact surface and at least one first non-contact surface positioned adjacent the at least one first sloped contact surface; and a second disk leaf having at least one second sloped contact surface and at least one second non-contact surface positioned adjacent the at least one second sloped contact surface, the first disk leaf and the second disk leaf being configured such that a gap is formed between the at least one first non-contact surface and the at least one second non-contact surface when the at least one first sloped surface is in contact with the at least one second sloped surface, wherein the at least one first sloped contact surface is formed in the first disk leaf as manufactured, and wherein the at least one second sloped contact surface is formed in the second disk leaf as manufactured; characterized in that the first disk leaf comprises at least two sloped contact surfaces, which are inclined in opposite directions with respect to a planar surface component of the first disk leaf, wherein the at least one first non-contact surface of the first disk leaf is parallel with respect to the planar surface component of the first disk leaf, and wherein the at least two sloped contact surfaces and the at least one first non-contact surface form at least one of a trench or peak within the first disk leaf, wherein the second disk leaf comprises at least two sloped contact surfaces, which are inclined in opposite directions with respect to a planar surface component of the second disk leaf, wherein the at least one second non-contact surface of the second disk leaf is parallel with respect to the planar surface component of the second disk leaf, and wherein the at least two sloped contact surfaces and the at least one non-contact surface form at least one of a trench or peak within the second disk leaf, and wherein the at least one of a trench or peak within the first disk leaf is configured to at least partially contact in mating alignment with at least one of a trench or peak within the second disk leaf. a first disk leaf having at least one first sloped contact surface and at least one first non-contact surface positioned adjacent the at least one first sloped contact surface; and a second disk leaf having at least one second sloped contact surface and at least one second non-contact surface positioned adjacent the at least one second sloped contact surface, the first disk leaf and the second disk leaf being configured such that a gap is formed between the at least one first non-contact surface and the at least one second non-contact surface when the at least one first sloped surface is in contact with the at least one second sloped surface, wherein the at least one first sloped contact surface is formed in the first disk leaf as manufactured, and wherein the at least one second sloped contact surface is formed in the second disk leaf as manufactured; characterized in that the first disk leaf comprises at least two sloped contact surfaces, which are inclined in opposite directions with respect to a planar surface component of the first disk leaf, wherein the at least one first non-contact surface of the first disk leaf is parallel with respect to the planar surface component of the first disk leaf, and wherein the at least two sloped contact surfaces and the at least one first non-contact surface form at least one of a trench or peak within the first disk leaf, wherein the second disk leaf comprises at least two sloped contact surfaces, which are inclined in opposite directions with respect to a planar surface component of the second disk leaf, wherein the at least one second non-contact surface of the second disk leaf is parallel with respect to the planar surface component of the second disk leaf, and wherein the at least two sloped contact surfaces and the at least one non-contact surface form at least one of a trench or peak within the second disk leaf, and wherein the at least one of a trench or peak within the first disk leaf is configured to at least partially contact in mating alignment with at least one of a trench or peak within the second disk leaf.
