DEVELOPMENT OF BINDERLESS CARBON-MESOPHASE FOR PRODUCTION OF HIGH STRENGTH GRAPHITES

Objective

Based on petroleum residues, different types of self sintering carbons (MMC) have been developed suitable for production of a new generation of high strength carbon and graphite materials. Four different grades of these so-called mesophase graphites have been tested as pistons in fired engines and sealing rings, respectively. In such heavily loaded systems the new materials exhibited improved performance compared to standard materials and especially environmental benefits.
The project deals with the development of carbon materials, based on mesophase, suitable for uses, especially in the manufacture of high-strength graphites for applications under severe conditions such as pistons in fired engines or sealing rings in heavily loaded systems. The raw material has only been available up to now from Japanese sources; manufactures takes plce in Japan or in the U.S.A. The aim of the project is to build up technology for the production of a raw material with homogeneous physical properties, suitable for binderless processing. To this end, in addition to an appropriate choice of oil residue, the optimization of the different variables in the carbonization process is vital. Moreover, the useful materials must be separated from the carbonized whole, and all process sections in the known production technology of graphite must be adapted and improved. The development of an economical heavy duty carbon material which combines the advantages of different carbon graphites used as sliding rings and pistons will clarify and demonstrate the potential of mesophase graphite. To this end, the project will include designing and manufacture of pistons and slidings from the graphite blocks prepared with the new carbon-mesophase material. The two types of artifacts will be tested under real conditions on engines and pumps.
