FIELD: aviation.
SUBSTANCE: structure of composite material made as composite material of fiber reinforced plastic, flowing in one direction and has plurality of holes, performed at intervals in a row in the same direction, that is stretching loaded and/or compressing loaded in one direction. Peripheral area around holes includes first phase obtained by bending composite material, reinforced with continuous fibres aligned in the longitudinal direction, so that the central line of width W of composite material zigzags between adjacent holes in one direction. Tensile stiffness and/or stiffness in compression in one direction of the peripheral area is lower than the tensile stiffness and/or stiffness in compression in one direction of the other area surrounding peripheral region.
EFFECT: increase the strength and weight reduction of the composite product.
