FIELD: textiles, paper.
SUBSTANCE: group of inventions relates to a three-dimensional woven preform, to fibre-reinforced composite material, to the method of forming a three-dimensional woven preform, to the method of forming the fibre-reinforced composite material. The three-dimensional woven preform comprises fabrics with a base located in a predetermined direction. The fabrics with a base located in a predetermined direction contain a part without tucks and a part with tucks. The parts with tucks of the said fabrics with a base located in a predetermined direction are connected to each other to obtain a continuous fibre in the circumferential and radial directions of all parts of the said preform.
EFFECT: invention provides improved physical and mechanical properties of products.
