Carbon composites reinforced by graphite grains

A new kind of composites – graphite grain/carbon (G/C) composites prepared by thermal gradient chemical vapor infiltration technology and elementary properties are investigated, and the microstructure evaluated. It is observed that pores among graphite grains are filled with pyrocarbon effectively, therefore, G/C composites with high density can be obtained. These composites offer the high temperature properties of carbon material, and excellent mechanical properties and isotropy.
