FIELD: process engineering.
SUBSTANCE: method of making structural part including tubular section 30 wherefrom extends structural element of composite. Proposed method comprises the following jobs: forming preform (49; 59; 69; 79; 99) including a stack of multiple superimposed layers so that layers in, at least, preform part to make structural section are secured to each other. Layers along, at least, preform another section to make section with pipe are separated to form tow opposed sheets (44; 54; 64; 68; 74; 94). Then, tube 30 is fitted between sheets of said connection section to make sheets surround the tube at least partially. Tube is connected to preform so that the tube make tubular section while preform makes structural element of structural part.
EFFECT: preset strength of mechanical joint, simplified process, smaller sizes.
