What is claimed is: 1. A sliding element for seals comprising: a fired preformed material including, a binder having 25 to 75 weight % carbonaceous impalpable powdery aggregate of non-graphitizing carbon and/or graphitizing carbon and 20 to 50 weight % synthetic resin, wherein the binder is blended
What is claimed is: 1. A sliding element for seals comprising: a fired preformed material including, a binder having 25 to 75 weight % carbonaceous impalpable powdery aggregate of non-graphitizing carbon and/or graphitizing carbon and 20 to 50 weight % synthetic resin, wherein the binder is blended with a carbon matrix having carbonaceous carbon fibers free of surface treatment in a range of 5 to 25 weight %, wherein said carbonaceous carbon fibers are randomly scattered in the carbon matrix, and wherein said carbonaceous carbon fibers are 5 to 30 μm in diameter, 50 to 300 μm in length, and have a Vickers hardness of at least 200. 2. The sliding element for seals according to claim 1, wherein a Vickers hardness of said carbonaceous impalpable powdery aggregate of non-graphitizing carbon and/or graphitizing carbon is 80 or more. 3. The sliding element for seals according to claim 1, wherein said synthetic resin includes at least one of phenolic resin, epoxy resin, furan resin, polyester resin, and naphthalene resin. 4. The sliding element for seals according to claim 2, wherein said synthetic resin includes at least one of phenolic resin, epoxy resin, furan resin, polyester resin, and naphthalene resin. 5. The sliding element for seals according to claim 1, wherein the sliding element for seals is used as one of a mechanical seal for a water pump, a mechanical seal for a compressor of a car air conditioner, a mechanical seal for a pump of industrial use and a mechanical seal for a pump of all purposes. 6. The sliding element for seals according to claim 2, wherein the sliding element for seals is used as one of a mechanical seal for a water pump, a mechanical seal for a compressor of a car air conditioner, a mechanical seal for a pump of industrial use and a mechanical seal for a pump of all purposes. 7. The sliding element for seals according to claim 3, wherein the sliding element for seals is used as one of a mechanical seal for a water pump, a mechanical seal for a compressor of a car air conditioner, a mechanical seal for a pump of industrial use and a mechanical seal for a pump of all purposes. 8. A seal assembly comprising a sliding element according to claim 1 and a mating sliding element comprised of a material having a Vickers hardness greater than that of the sliding element of claim 1. 9. The seal assembly according to claim 8, wherein the mating sliding element is comprised of silicon carbide. 10. A process of manufacturing a sliding element for seals, comprising the steps of: blending a source material binder comprising 25 to 75 weight % carbonaceous impalpable powdery aggregate of non-graphitizing carbon and/or graphitizing carbon and 20 to 50 weight % synthetic resin with 5 to 25 weight % carbonaceous carbon fibers that are free of surface treatment; mixing, kneading and molding the blended material to a preform; and firing the preform at a predetermined temperature, wherein said carbonaceous carbon fibers are 5 to 30 μm in diameter, 50 to 300 μm in length, and have a Vickers hardness of at least 200. 11. The process of manufacturing a sliding element for seals according to claim 10, wherein said synthetic resin includes at least one of phenolic resin, epoxy resin, furan resin, polyester resin, and naphthalene resin, and wherein a firing temperature for said firing is 800 to 1500째 C. 12. The sliding element for seals according to claim 1, wherein said carbonaceous carbon fibers are manufactured from one of polyacrylonitrile series carbon fibers and pitch series carbon fibers. 13. The sliding element for seals according to claim 1, wherein said carbonaceous carbon fibers withstand a maximum heat treatment temperature of 1500째 C. 14. The process of manufacturing a sliding element for seals according to claim 10, wherein said carbonaceous eaton fibers are manufactured from one of polyacrylonitrile series carbon fibers and pitch series carbon fibers. 15. The process of manufacturing a sliding element for seals according to claim 10, wherein said carbonaceous carbon fibers withstand a maximum heat treatment temperature of 1500째 C.
