    Strong and tough Hi-Nicalon SiC fiber reinforced reaction-bonded silicon nitride matrix composites (SiC/RBSN) have been fabricated by the fiber lay-up approach. Commercially available uncoated and PBN, PBN/Si-rich PBN, and BN/SiC coated SiC Hi-Nicalon fiber tows were used as reinforcement. The composites contained ∼24 vol% of aligned 14 μm diameter SiC fibers in a porous RBSN matrix. Both Development of SiC/SiC Composites by the Melt Infiltration Process S.R. Lee, Y. Katoh, and A.
