Summary

A continuous carbon fiber/silicon nitride matrix composite material has been produced by an inexpensive method. According to this method, the space between 3D carbon fiber preform is filled with a S3N4 powder by a pressure infiltration method. High particle packing densities are achieved within the fiber preform in this way. The compact body is heat treated to form a porous framework without shrinkage, which is then strengthened with an inorganic matrix synthesised from a liquid preceramic polymer. The densification degree, microstructure, thermal and mechanical properties of the composite material are characterized. The C/Si3N4 composite material pyrolyzed at 1300 °C is considered to be a very promising material for low temperature applications such as brake discs for rapid train systems.
