    摘要: A novel composite material is obtained by winding a reinforcing yarn, made of refractory fibers, onto a form, and a mandrel, the wound yarn being impregnated, as it is wound, with a “slip” composed of a liquid resin mixed with fillers composed of particles of refractory material. The reinforcing yarn is composed of linear fibers and of fibers forming protruding loops which confer a three-dimensional texture on the wound reinforcement. The yarn preform composed of the reinforcing yarn impregnated with “slip” is crosslinked according to a defined heating cycle comprising several temperature gradients of different durations. The crosslinked yarn preform is subsequently machined so as to bring the composite material component thus produced to the desired shape. The composite material component thus shaped can optionally be reinforced by overwinding on its external face with a reinforcing yarn preimpregnated with a resin chemically compatible with the resin constituting the material.

    摘要: 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 Periodically, the water in the tank is withdrawn and the tank stripped of its deposits such that subsequent dismantling operations can be carried out under proper conditions.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.

    摘要翻译: 提供了一种固体推进剂发动机安全拆卸并符合已报废环境标准的方法。 对于每个要拆卸的发动机,将其安装在静态试验台上,浸在装满水的罐中,并开始使用推进剂在水下使用。 因此,燃烧产物(气体或冷凝物)的可溶部分被捕获在罐中的水中,而不溶性固体产物下降到罐的底部。 以这种方式清空其燃料的发动机体,然后将烟火放置为惰性,然后拆开或拆卸。 定期地,罐中的水被取出,并且罐被剥去其沉积物,以便随后的拆卸操作可以在适当的条件下进行。 所有回收的燃烧产物都送到适当的后处理厂。 该方法允许高拆解率。
