A method is provided for solid-propellant engines to be dismantled safely and in accordance with environmental standards having been scrapped. For each engine to be dismantled, it is mounted on a static test rig, immersed in a tank filled with water and started such that propellant is used up under the water. The soluble part of the combustion products (gases or condensates) thus remains trapped in the water in the tank while the non-soluble solid products drop to the bottom of the tank. The body of the engine emptied of its fuel in this way and rendered pyrotechnically inert is then taken apart or disassembled. Periodically, the water in the tank is withdrawn and the tank stripped of its deposits such that subsequent dismantling operations can be carried out under proper conditions. All of the combustion products recovered are sent to appropriate reprocessing plants. The method allows high dismantling rates.

Abrégé

The method according to the invention allows solid-propellant motors to be dismantled safely and in accordance with the environmental standards after they have been returned for reprocessing. It consists chiefly, for each motor that is to be dismantled, in mounting the motor on a static test rig, in immersing the rig in a tank filled with water and in starting the motor so that the propellant is used up underwater. The soluble part of the combustion products (gases or condensates) thus remains trapped in the water of the tank while the non-soluble solid products drop to the bottom of the tank. The motor body thus emptied of its fuel and rendered pyrotechnically inert is then dismantled or stripped down.

Abrégé

The invention consists of a novel composite material obtained by winding a reinforcing yarn (21), made of refractory fibres, around a form, a mandrel (47), the wound yarn being impregnated, as it is wound, with a "slurry" constituted of a liquid resin mixed with fillers constituted of particles of refractory material. The reinforcing yarn (21) is constituted of linear fibres and fibres that form protruding loops which give the wound reinforcement a three-dimensional texture. The yarn preform constituted by the reinforcing yarn impregnated with "slurry" (41) is crosslinked according to a defined heating cycle comprising several temperature ramps of different durations. The crosslinked yarn preform is then machined so as to fashion the element of composite material thus produced in the desired form. The element of composite material thus formed may optionally be reinforced by overwinding on its outer face a reinforcing yarn previously impregnated with a resin that is chemically compatible with the resin constituting the material.
