ABSTRACT:
The present invention relates to a process for manufacturing thermal protection material or piece. According to the process of the invention, a first solution is prepared, comprising a dispersant agent non-solvent of the resin, an emulsifying agent in which said fibers are suspended, and a second solution comprising said liquid resin selected from the thermostable and thermosetting resins having a fixed carbon content greater than 45% by weight, an emulsifying agent identical to that used in the first solution, a solvent of the resin and a dispersant medium identical to that used in the first solution and miscible with said solvent, the first and the second solution are mixed until a homogeneous liquid phase is obtained, the material or the piece is formed, drained, dried and hardened by an appropriate baking.
Application of the protection material thus obtained for the equipment of a missile propellant stage.
