ABSTRACT:
There is disclosed a vibration dampener comprising a body for disposition tween two relatively movable members, the body being formed from a carrier of a gel material and particles having electrorheological properties embedded in the carrier with the particles electrically aligned and pseudo-bonded. Upon a displacement force being applied to the body, as by one of the members, the particles resist motion relative to other of the particles. There is further disclosed a method for making the aforesaid vibration dampener wherein the dampener has a current passed through it while the carrier cures into a gel material.
