Abstract
Apparatus is provide for the fabrication of fiber composites composed of a fiber-reinforced vitreous or glass-ceramic matrix by winding fibers preimpregnated with constituents of the matrix onto a mandrel. The apparatus includes a furnace into which a winding mandrel can be introduced; elements for driving the mandrel in rotation around its axis inside the furnace; transit elements including a slot parallel to the axis of the mandrel positioned in the wall of the furnace for delivering fibers into the furnace; elements including a head for delivering fibers from supply spools positioned outside the furnace to the mandrel inside the furnace via the transit elements; and elements for actuating and controlling delivery of fibers and driving in rotation of the mandrel comprising elements for actuating and controlling the elements for driving the mandrel and the head for delivering the fibers as a function of winding parameters.
