  • Patent number: 6706132
    Abstract: Methods for fabricating laminations to form structural elements of predetermined shapes (120, 220, 420, 520, 620) are provided. Laminations include parts (22, 24) fabricated from the tread portion (42) of discarded rubber tires. The parts are typically arranged in layers with various relationships therebetween. The parts are pressed to remove all voids therebetween causing dynamic tension which creates rigidity and then bonded with methods including vulcanization, chemical vulcanization, epoxy and adhesive.
