Method of fabricating an isolator mount

Abstract

A method of fabricating an isolator mount is presented. The method includes plasticating a polymeric material, forcing the polymeric material through a shaping die, forming a continuous extrusion so that shear flow aligns a plurality of energy damping particulates within the polymeric material along a preferred direction, and cutting the continuous extrusion after the forming step. In yet another embodiment, the fabrication process includes extruding a polymeric material having a plurality of energy damping inclusions therein, inducing a magnetic flux density field so as to align the energy damping inclusions in a preferred direction before cooling of the polymeric material, and inducing a magnetic bias across the polymeric material so as to form an RL equivalent circuit.
