Abstract: Thermal protection material coating of an aggregate of mineral fibers, in particular carbon or silicon, is provided with at least one coat of a silicon-based material covering at least the area exposable to the flaking or crumbling sources of the thermal protection device. The coating is especially applicable to thermal protection structures.

Abstract: Arrangement for the thermal protection of an object, particularly a space vehicle, such as a space missile, including a frame structure covered with thermal insulating material, wherein the material is made of an aggregate of carbon or silica short fibers, the fibers being linked together by means of a binder made of the same constituent and possibly of an appropriate resin. The aggregate is in the form of at least one monobloc element, which is accordingly shaped and dimensioned, and adhered onto the frame structure.

Abstract: A reservoir for storing a pressurized fluid is disclosed, having a longitudinal axis and comprising a central tubular portion closed at its ends by two bottoms, one at least of which bulges outwardly and is provided with a neck, and also a method of manufacturing such a reservoir.According to the invention, said reservoir is formed by a tubular shell of a composite fiber-thermoplastic binder material and two end pieces made from a thermoplastic material strengthened with reinforcement fibers, said shell and said end pieces being secured solidly together by local heat-melted zones.

Abstract: The tube, composed of a structural portion (1) of composite fibers encapsulated with thermosetting matrixes playing the part of a binder and obtained by filament winding, is provided with at least one inner coating (2) of a fibrous composite material impregnated with a thermoplastic binder, which is directly adjacent to the tubular portion formed by the structural portion (1) with the thermosetting binder.Application to oil production tubings.

Abstract: A machine for weaving fibers of glass, Kevlar, carbon and the like including a rotary assembly with two plates defining therebetween a weaving chamber. The lower plate has sliding fingers at its periphery and the upper plate has fixed fingers in line with the sliding fingers occupying positions where they are moved away from each other in at least one sector of the support frame and positions in which they are in contact with each other in at least another sector of the support frame for forming continuous columns enclosing the weaving chamber. The fingers serve as support for the radial threads. Hooking platelets are provided on the periphery of the support frame for ensuring movement of the sliding fingers perpendicularly to the lower plate, and movement of the platelets on said fingers as a function of their position with respect to the support frame.
