Abstract
A ceramic die for a hot press is provided, along with a method of constructing a ceramic die. The ceramic die includes a ceramic die body defining a mold surface configured to shape a part during a superplastic forming process. The mold surface defines at least one curved surface and at least one non-curved surface, spaced apart from the at least one curved surface. The ceramic die also includes a plurality of fibers disposed within the ceramic die body. The plurality of fibers may be preferentially located proximate the at least one curved surface such that a first portion of the ceramic die body proximate the at least one curved surface has a greater percentage of fibers than a second portion of the ceramic die body proximate the at least one non-curved surface.
