Abstract
Within examples, elastomeric apparatuses for use in manufacture of a composite component, and methods for altering a surface rigidity of an elastomeric apparatus for use in manufacture of a composite component are described. In one example, an elastomeric apparatus comprises an elastomer housing, and a plurality of magnets within the elastomer housing at predetermined positions to provide surface rigidity to the elastomer housing based on one or more alignments of certain magnets of the plurality of magnets due to magnetic forces. An increase in temperature causes a loss in one or more of the magnetic forces of one or more of the plurality of magnets resulting in a reduction of stiffness of the elastomer housing at corresponding predetermined positions.
