Composite mold and method for making the same

摘要

A composite mold has a composite structure defining a molding surface having a desired shape. The composite structure is comprised of a sintered material formed by sintering a mixture that includes tungsten carbide particles and carbon nanocapsules. Preferably, the mixture further includes noble metal particles. A method for making a composite mold includes the steps of: providing a first mold having a desired shape; placing a mixture comprising carbon nanocapsules and tungsten carbide particles into the first mold; and sintering the mixture of carbon nanocapsules and tungsten carbide particles, thereby forming a composite mold having a composite structure and defining a molding surface.
