Abstract

Cf‐ZrB2 and Cf‐ZrB2‐SiC ultra high temperature ceramic matrix composites were produced using slurry infiltration in the 2D woven carbon fabric and hot pressing at 2000°C. The mixing time and amount of solid loading of the ZrB2‐SiC slurry were found to have a significant effect on both microstructure and mechanical properties and were optimised to obtain an agglomerates‐free composite. The ZrB2‐SiC slurry with a solid loading of 20–30% was found to be effective for infiltration within the intra pore in carbon tows. The composites have a nearly completely dense matrix layer with a porous matrix within the fibre layers. The fabricated 2D woven Cf‐ZrB2 and Cf‐ZrB2‐SiC composites were non‐brittle.
