Summary

The process of fabricating Blackglas™ ceramic matrix composites reinforced with nitrided Nextel 312R 3-D preform was investigated. The composites were densified through five infiltration/pyrolysis cycles using the Blackglas siloxane infiltrant. Changes in density, porosity, and bend strength were monitored at each reimpregnation step. A model based on pyrolysis volume yield was developed to predict the weight gain and open porosity of the composites.
