A process for producing a body having a porous matrix of at least one recrystallized ceramic material, or for producing a similar fiber-reinforced body, includes shaping a raw material batch which contains a raw material powder and then sintering. A raw material powder is used which has grain size distribution of a fine grain fraction of an average grain size of at most approximately 2 &mgr;m and a coarse grain fraction of an average grain size of approximately 1.5 &mgr;m to approximately 30 &mgr;m, and the sintering process is carried out at a temperature of at most approximately 1,800&deg; C. Because of the selected grain sizes and grain size distributions, the sintering process can be carried out at lower temperatures. In particular, reinforcing fibers can be worked in which can withstand higher sintering temperatures. By defining the grain size of the powder, a porosity can also be set which permits a good impregnating with organic and/or inorganic substances.

Undesirable attenuations are avoided in a light-conducting cable by providing a certain play between the coated light-conducting fiber and its outer protective casing which may include a reinforcing sheathing surrounding the coating and surrounded by an outer casing. Such play is achieved by temporarily providing a removable material radially inwardly, or in, or radially outwardly of the sheathing and then removing such temporary layer by chemically dissolving the layer, or melting, or evaporating the layer through the outer casing which is made permeable for this purpose.

A reaction mass for a launching tube having a centrally positioned propellant charge for propelling a missile at its forward end and a reaction mass located rearwardly of the propellant charge which is propelled at the rear end, comprises an inert, readily fragmentizing, expellable reaction mass comprising a glass material which is internally prestressed and which disintegrates at the launch. The reaction mass is advantageously in the form of a glass cylinder which is either connected to a metallic pusher member arranged rearwardly of the propellant charge which is pushed by the ignition of the charge in a rearward direction, or it may comprise a glass cylinder which includes its own pusher head formation. The pusher itself is arrested by a brake positioned at the rear exit. In addition, the rear exit is closed by a diaphragm which may shatter after ignition of the propellant charge. The reaction mass may also comprise a front pusher face which is engaged with a rear brake positioned at the rear opening or it may comprise a plurality of layers of glass held to a pusher head which is arrested at the rear opening. In still another embodiment, the glass may comprise a plurality of flat discs held together in an assembly to a pusher member.
