FIELD: textiles, paper.
SUBSTANCE: fabric preform used to reinforce a composite structure, comprising a central part (6, 10), having interwoven layers. The preform also comprises a first and second end parts (4, 12) having independent fabric layers (50) which are woven in one piece with the interwoven layers in the central part (6, 10) and which extend along the entire length of the preform. Between the independent fabric layers (50) in the first and second end parts the diagonal interlayers (26) are inweaved. The first and second end parts may have reinforcement (71) extending through the entire thickness, comprising reinforcement fibers that traverse the independent fabric layers and the diagonal interlayers, coupling them together.
EFFECT: improvement of the method.
