Abstract
The invention is concerned with apparatus for producing a shaped filamentary structure and more particularly, a filamentary structure which can be subjected to further processing to produce a carbon-carbon product. A specific use of the invention is in the production of discs for use in aircraft braking systems. The invention comprises an apparatus comprising an open-topped receptable for assembled segments formed by cutting a plurality of segments from a layer of needle punched filamentary material; a needling head located over only part of the receptacle; means for rotating the receptacle to bring a complete annulus of the filamentary segments in it under the needling head and a support located inside the receptacle and means for rotating the support with the receptacle, and lowering the support relatively to the receptacle during the needling operation.
