FIELD: manufacture of blanks for reinforced composite material. SUBSTANCE: flat fabric has first part, second part, which may be bent from first part, and plurality of threads for connecting first part to second part. Thread running from first part to second part defines thread path having portion of thread made shorter than said path and portion of thread made longer than said path. Upon bending of second part from first part, shorter portion of thread draws longer portion of thread along said path so as to compensate bending. Flat blank may be bent to obtain final configuration without creating of undesired fabric deformations. EFFECT: improved structure of reinforced composite material. 6 cl, 8 dwg
