Abstract
This phase I research proposes an efficient approach to develop a reliable chemical vapor infiltration (CVI) process for HfB2-HfC-SiC matrices for carbon fiber composites and chemical vapor deposition (CVD) processes for depositing coatings for the same compositions, and; second, to design, fabricate, and evaluate ultra-refractory CMCs consisting of a carbon fiber reinforcement reinforcing a functionally graded matrix of HfB2-HfC-SiC graded to SiC. These advanced, lightweight materials are likely enabling for future propulsion goals. The HfB2-HfC-SiC monolithic material has been shown to exhibit high temperature performance superior to all other materials tested under reentry conditions. The oxidation layer formed on these monolithic compositions was extremely tenacious, displaying no spallation after cooling from 2200
