Abstract
Within examples, methods and systems for a multi-state bladder or elastomeric apparatus for manufacture of composite material are provided. In one example, the elastomeric apparatus comprises an elastomer housing, and magnetic components within the elastomer housing such that application of a magnetic field to the elastomer apparatus changes a rigidity state of the elastomer housing to a secondary state. The secondary state is supportive of a surface compaction applied to the elastomer housing. The elastomeric apparatus may also include rods within the housing extending along the housing, and the magnetic components are mounted to the rods in a rotatable manner. The magnetic components can react to a magnetic field in a way that aligns the magnetic components by rotating on the rods to cause the housing to have a rigid surface state, and to cause the housing to have a flexible surface state in absence of the magnetic field.
