StarPCS™ SBMC-900

1 of 4 products in this brand
StarPCS™ SBMC-900 are carbon fiber reinforced molding compounds containing a discontinuous carbon fiber, a specially formulated StarPCSTM polycarbosilane resin, and refractory particulate. SBMC-900 and SBMC-998 can be used in the cured state, but are specifically designed for use as a ceramic matrix composite (CMC) thermal or mechanical structure.

Technical Details & Test Data

Technical Details

Green Body Curing:

  • To create a green body, StarPCSTM BMCs are compression molded using standard compression molding techniques, tooling, and typical pressures, and are cured at temperatures between 180-250°C.

Ceramic Matrix Composite (CMC):

  • To create high temperature ceramic matrix composite structures, these green bodies are pyrolyzed to temperatures between 850°C (minimum) and 1,200°C at atmospheric pressure and in inert environments to create a porous ceramic matrix preform. Vacuum infiltration fills the pore volume to allow creation of an amorphous silicon carbide CMC. Ideal infiltration polymers include StarPCSTM SMP-10 or SMP-877.
