High temperature engine protection

Sending payload to Space is a particularly critical mission.  The main goal is to make sure the launching system safely take off and maintain its trajectory objectives. This is achieved by efficiently counterbalancing the effect of gravity through the use of propulsion engines that release a massive quantity of energy in a short period time.
Along the combustion path, this deflagration implies specific thermomechanical conditions that generally demonstrate high temperatures and pressures to which surrounding materials need to resist in order to keep the rest of the system intact.
Beyond thermal insulation, ablation is the main phenomenon enabling such protection. Sacrificial materials are used along the combustion path in order to consume thermal energy by transforming the solid sacrificial material in gas. This endothermic reaction allows the launching system structure to remain protected from the extreme heat and pressure generated in the combustion chamber.
Quartzel® products are perfect materials for this application as they undergo a sublimation mechanism above 1600°C taking quartz from a solid directly to a gaseous state. Quartzel filaments can be used in various forms (yarn, roving, chopped etc.) and processed through multiple textile technics (woven, braided, knitted etc.) in order to adjust the fiber orientation in the composite that will constitute the ablative parts.
