<p>Non-destructive damage evaluation of rocket engine combustion chamber was investigated by using replica method through rapid setting silicon rubber molding agent. Scratch marks, grinding marks and an oxide film on the combustion side surface of the repeated burning test were successfully transferred to this replica sheet without complicated surface treatment. Observation results of the sampled replica showed the traces of the oxide film formation, disappearance of the grinding marks and crack formations on the oxide films due to redox reaction during repeated uses. The surface roughness of light and dark lines parallel to the cooling grooves with cracked oxide film was evaluated by laser scanning microscope. The surface roughness parameter could be useful to evaluate the damage of the reusable sounding rocket engine.</p>
