METHOD OF MANUFACTURE OF COMPOSITE STRUCTURAL ELEMENT, COMPOSITE STRUCTURAL ELEMENT AND WIND-DRIVEN POWER PLANT Russian patent published in 2018 - IPC F03D1/06 B29C70/00 

FIELD: power industry.

SUBSTANCE: method of manufacture of composite structural element, in particular for wind-driven power plant, which includes a lot of, at least, two-component composite shaped parts, wherein the first component is formed from the core shaping material and the second component is formed as a part of the connecting layer, the shaping core material is formed, in the prism shape, in the form of a prismatic body with a polygonal base. The polygon of the base has a basis and an angle to the basis, which is from 30° up to 60°, and connect a set of prismatic bodies, and on the joined sides, the functional orientation of the connecting layers is performed in such a manner that the connecting layer passes at an angle 30-60° to the basis surface of at least one of the prisms adjacent to each other. The second component is formed as a woven mat, the woven mat is placed between the first and the second prismatic bodies and connected with the shaping core of the prismatic bodies and the core shaping material is being obtained by extrusion. The composite structural element is connected by a hot joint.

EFFECT: increase bending and shear stiffness.
