Fibrous substrates for the production of carbon and/or ceramic (including mixtures of these) fiber reinforced carbon and/or ceramic (including mixtures of these) composites and to methods of manufacture of same. A shaped filamentary structure comprising at least a first braided filamentary tape layer of a width generally corresponding to that of the filamentary structure to be formed, the first braided filamentary tape layer superposed upon and joined to least one other filamentary layer by needlepunching to produce cross-linking of the layers by filaments displaced out of the layers and extending in a direction generally perpendicular to the faces of the layers, and methods of making same. The structure may include a plurality of hellically wound braided tapes arranged to form a flat, hollow annulus having a plurality of interleaved braided layers. The structure may be used in the production of friction discs.
A method of producing a near net shape filamentary structure having a width comprising the steps of forming a braided filamentary tape of a width generally corresponding to the width of the filamentary structure to be formed;
A method of producing a near net shape hollow flat annular filamentary structure comprising the steps of forming a braided filamentary tape of a width generally corresponding to the radial distance between the inside diameter periphery and the outside diameter periphery of the annular structure to be formed;
A shaped filamentary structure having a width, the structure comprising at least a first braided filamentary tape layer of a width generally corresponding to the width of the filamentary structure to be formed superposed upon and joined to least one other filamentary layer by needlepunching to produce cross-linking of the layers by filaments displaced out of the layers and extending in a direction generally perpendicular to the faces of the layers.
