Summary

Pyrolysis of organometallic polymers was investigated as a low temperature processing route for the fabrication of ceramic matrix composites. Two polymeric precursors, polycarbosilane (PCS) and polyinylsilane (PVS), were used in this study. Ceramic yields as high as 85 wt% are possible when PCS is used as the precursor. Dimensional instability and microcracking encountered during pyrolysis can be overcome by the addition of suitable ceramic fillers. Preliminary mechanical testing results of continuous, Sic fiber-reinforced ceramic matrix composites indicate the fiber/matrix interface is important.
