Abstract Scope Ultra-high temperature ceramic composites (UHTCMCs) have shown considerable potential to withstand the extreme conditions found in aerospace applications. Among the most common processes currently investigated to produce UHTCMCs, polymer infiltration & pyrolysis (PIP) offers advantages in terms of relatively low processing temperatures (~1000C) and the possibility of fine control of the matrix microstructure that can potentially overcome the long manufacturing time required to obtain a satisfactory densification level. Doping the polymer with transition metals allows the formation of high melting point oxides that increase the stability of the resulting protective silica glass under typical thermo-ablation conditions. In this work, the feasibility of using modified preceramic polymers to densify ceramic matrix composites for aerospace applications is being researched. Low-porosity green samples are manufactured with woven or preform carbon fibre structures and a ceramic slurry, then densified with a modified commercial polysilazane and tested in subsonic ablation conditions in the 2000-3000C range.
