Abstract

A method and an apparatus for producing a radially aligned magnetorheological elastomer molded body containing a matrix resin and a magnetic filler are provided. The method includes the following: placing a permanent magnetin at least one position selected from positions that are spaced from a metal moldhaving a cavityand located above and below the center of the metal mold; providing a closed magnetic circuit that allows a magnetic fluxgenerated by the permanent magnetto pass through the metal moldfrom a side thereof, filling the cavitywith a composition containing the matrix resin and the magnetic filler; and molding the composition while the magnetic filler is radially aligned. With this configuration, the elastomer material is molded while the magnetic filler is radially aligned by using the permanent magnet.
