Summary

Identification of conditions for the successful infiltration of HfB2 matrix composites was established by modeling of the infiltration process based upon shorter time CVD experiments. A model was utilized to predict the experimental infiltration of fine cylindrical capillaries. From this model, a two stage process was selected to allow infiltration of the fine capillaries within a fiber bundle and subsequently the larger pores between bundles. The properties of the fabricated Cf/HfB2 composites were also determined.
