1. A rotational spring dampener, comprising:
a compression limiter having an exterior surface and a mounting hole that is configured to receive a fastener;
a first disk disposed at a first end of the compression limiter, wherein the first disk is disposed around and in contact with the exterior surface of the compression limiter;
a second disk disposed at a second end of the compression limiter, the second end opposite the first end;
a tensile member connected to the first disk and the second disk; and
a brake connected to the tensile member and positioned adjacent to the compression limiter,
wherein the tensile member is configured to adjust contact between the brake and the exterior surface of the compression limiter, and
wherein the tensile member comprises a block copolymer.
