Abstract
Dampers made from polymers modified with nanomaterials (e.g. carbon nanotubes). This novel viscoelastic material has significantly improved damping characteristics making nano-modified polymers excellent materials for viscoelastic dampers, including highly customizable materials and geometries tailored to achieve good damping properties and proper shear stiffness and shear capacity.
Claims8
An energy dissipation mechanism for dissipating a force during a loading event comprising:
- a first plate and opposingly located second plate;
- a dampener located in between said first and second plates;
- said dampener is configured to deform nonlinearly when a load is applied to dissipate energy;
- said dampener is interlocked with said first and second plates;
- said dampener includes a plurality of flanges;
- said first and second plates including a plurality of openings that match the configuration of said flanges;
- said flanges seat within said openings to interlock said dampener with said first and second plates
- each of said flanges include a rounded distal end that seats within openings having the same rounded shape;
- and
- said flanges configured to rotate within said openings when a load is applied.
