Silica and graphite-phenolic ablative materials were examined before and after test firing in a rocket engine nozzle. Chemical, thermal, and physical characterizations of the post-fired nozzle chars were performed in depth at selected nozzle locations. Similar characterizations were also performed on raw billets and laboratory oven-prepared chars. The fired nozzle char property determinations were performed on various layers removed from the char zones and included carbon, hydrogen, oxygen, and ash analysis, trace metal analyses, density, porosity, X-ray diffraction analysis, optical reflectance, photomicrographic analysis, specific heat, and thermal conductivity. Data are presented in tabular and graphical property profile format.
