    摘要： A linked multilayer woven fabric for use in the production of structural composite materials has a base weave comprising twenty-eight weft yarns which are distributed in eight columns containing alternately four superimposed yarns and three superimposed yarns such that they are in a staggered arrangement on seven levels, and twelve warp yarns which are arranged in four parallel planes each containing three superimposed parallel warp yarns. In each plane, one of the warp yarns connects the upper outermost weft yarn of one of the weft columns containing four weft yarns to the corresponding weft yarn of the following base weave group via the upper intermediate weft yarn of the weft column midway between the other two columns, a second of the warp yarns connects the upper intermediate weft yarn of said one column to the corresponding weft yarn of the following base weave group via the lower intermediate weft yarn of said midway column, and the third warp yarn connects the lower intermediate weft yarn of said one column to the corresponding weft yarn of the following base weave group via the lower outermost weft yarn of said midway column.

    摘要： A process for moulding high strength elongated parts made of a fibre-resin composite material, especially turbomachine blades such as fan blades, is disclosed wherein a plurality of heating and cooling elements are arranged within the body of the mould at intervals along the length of the mould cavity, and the liquid resin which is injected at one end into the mould cavity containing the fibre preform is polymerized progressively from the opposite end of the mould cavity, while maintaining the supply of liquid resin under pressure to the cavity, by successively de-activating the cooling elements, which maintain the resin in the liquid state, at predetermined time intervals starting from said opposite end of the mould cavity and progressing in turn towards said one end, and in synchronism therewith successively activating the heating elements to raise the temperature of the resin to the polymerizing temperature progressing in turn from said opposite end to said one end of the mould cavity. The process enables shrink cavities in the finished part to be avoided.

    摘要： A turbomachine blade, particularly a fan blade for an aircraft jet engine, is made of a composite material comprising reinforcing fibres embedded in a thermosetting resin matrix, wherein the reinforcing fibres form a multilayer woven fabric in which the warp fibres of each layer are interwoven not only with the weft fibres of the layer but also with the weft fibres of at least the layers immediately above and below it so that the layers are all interconnected. Also, each layer only partly covers the layer below it so that the ends of the warp and weft fibres of a layer extend to near the surface of the blade, and the thickness of the blade at any point is determined by the number of layers present at that point.
