Abstract
A hybrid mandrel for forming a composite part may comprise a core and a sleeve located around the core. The core may include a rigid material. The sleeve may comprise an elastomeric material. The part may be formed by locating the hybrid mandrel in an injection mold, depositing a molten resin around the hybrid mandrel, curing the molten resin; and removing the hybrid mandrel.
