ABSTRACT:
Disclosed herein is a method of manufacturing a piston comprising the steps of providing a shell comprising graphite fibers formed to include the general shape of an open-ended cylinder having an outer periphery, and casting metal to form at least a portion of the piston so that the shell is included and at least a portion of the outer periphery of the shell is exposed. Also disclosed herein is a piston comprising a mesh of graphite fibers having a generally cylindrical shape and defining mesh voids, structural material filling at least some of the mesh voids so that an exterior cylindrical surface of the piston is defined to include at least portions of at least some of the fibers.
