A multi-layer elastomeric tooling for the manufacturing of composite structures is disclosed. The tooling comprises an elastomeric base material with an outer layer of fluoroelastomer. The base material can, in certain embodiments, be selected for its mechanical or thermal performance or low cost without the limitation of being a contact material. The outer material can, in various embodiments, have inferior mechanical properties, or durometers different than the base material or can be a contact or barrier material.
