Abstract
This paper reports the ability to use a commercial polysilazane† † PYROFINE PV from Elf Atochem. Centre de Recherche Rhône-Alpes, rue Henri Moissan, 69310 Pierre-Bénite, France. as matrix precursor for the manufacture of ceramic matrix composites. By pyrolysis under nitrogen in the temperature range 1000-1400 °C this polysilazane leads to an amorphous silicon carbonitride with a ceramic yield around 65 wt%. The rheological behaviour and the thermal decomposition of the polysilazane have been studied. Parameters for the impregnation and pyrolysis cycles required by the manufacture of composites are also proposed.
