Zusammenfassung:Filled thermoplastic pitch comprising particulate filler and advanced mesophase pitch having a TMA deformation temperature of at least 400 DEG C., and a method for the manufacture thereof. The filled thermoplastic pitch may be shaped and densified in one or more thermoforming operations. The resulting preform may be thermoset and carbonized in ordinary baking operations without requiring molds and pressurized vessels.
