Process of producing a ceramic/fiber composite using a molten polysilazone

摘要

The invention relates to a process for the production of a ceramic/fiber composite. The process comprises impregnating fibers with a molten polysilazane in a first step, converting the polysilazane in the fibers into the infusible state in a second step and, in a third step, heating the impregnated fibers to 800 DEG to 2000 DEG C. in an atmosphere of nitrogen, noble gas, or ammonia.
