FIELD: textile industry.
SUBSTANCE: invention relates to a method for manufacturing a part of composition material containing a case extended with reinforced fastening end. According to the method, a draft fiber workpiece is formed from three-dimensional fabric containing warp threads oriented in the main direction with separation by absence on at least one end of the draft fiber workpiece to obtain at least two sets of rigidly connected layers. Flat displacement of at least one set of rigidly connected layers is performed by displacement of the end edge of this set of rigidly connected layers communicating to this end edge the shift movement oriented parallel to the set of rigidly connected layers and perpendicular to the main direction to tilt warp threads of this set of rigidly connected layers relatively to the main direction. The draft fiber workpiece is shaped to obtain a shaped workpiece. A matrix is injected to the shaped workpiece.
EFFECT: invention provides increased mechanical properties of the product.
