FIELD: textiles, paper.
SUBSTANCE: preform has a three-dimensional woven configuration with weft fibres interwoven with providing weaving layer-to-layer of layers of warp fibres and weaving of fibres inside each layer. And at least one leg emerges from the base. The base and each leg comprise at least two layers of warp fibres. The legs may be parallel to each other or located at an angle to each other and/or may extend sinusoidally in the weft and/or warp direction. Preferably, the outer ends of the base and/or the legs are made in the form of narrowing formed by the end layers of warp fibres having a stepped pattern.
EFFECT: obtaining woven preform for use in reinforced composite material which may be woven smooth and folded into its final form.
