StarPCS™ SBMC-843 is a discontinuous carbon fiber reinforced molding compound containing carbon fiber, a Starfire proprietary polysiloxane resin, and refractory particulate. SBMC-843 contains a Polyramic® thermosetting resin which cures at temperatures between 200-310°C, and functions as a high temperature carbon fiber reinforced structure with a silicon oxycarbide ceramic matrix. Compression mold curing produces a green fiber reinforced polymer matrix composite (PMC) material. Further processing to 850°C minimum in inert environment results in an amorphous silicon oxycarbide ceramic matrix composite (CMC) to be used with different infiltration polymers or materials. Ideal infiltration polymers include Polyramic® SPR-212, SPR-212 based slurries (SL-227, SL-480), and other Starfire® polysiloxane products.
