METHOD FOR ENHANCING THE SEALING POTENTIAL OF FORMABLE, DISPOSABLE TOOLING MATERIALS

摘要

Methods for enhancing the sealing potential of a formable, disposable tooling core for use in the fabrication of composite articles, the method comprising obtaining a pre¬ formed tooling core from a mold, the tooling core having a prepared working surface; applying a liquid prepolymer mixture configured for rapid polymerization at ambient conditions over at least a portion of the working surface; and rapidly polymerizing the prepolymer mixture to form a non-porous sealant over the portion of the working surface. Also, methods for manufacturing tooling members and composite articles utilizing a disposable tooling core.
