Application of Basalt Fibre Composites for Wind Turbine

Abstract

Currently. in many countries, studies are undertaken to study basalt fibre, which is one of the interesting reinforcing materials for polymer composite materials. Unlike traditional materials, when using fibre composites, product production and material formation occur simultaneously. Therefore, this work carried out the study of the material in conjunction with the study of technologies for the manufacture of products. The results of the study of the mechanical properties of basalt fibre produced in Georgia and the results of studies carried out to determine the effectiveness of its use as a reinforcing agent in the manufacture of products are presented. Experiments to determine the strength were carried out both for a single fibre and for a fabric woven from it. This work has developed some technologies for the manufacture of two types of products - high pressure cylinders and rotor blades of wind power plants. In the first case, for reinforcing the polymer composite, a bundle of threads was used, and in the second case, a fabric woven from basalt fibre was used as a reinforcing material. The experiments to determine the material mechanical performance were carried out for a single fibre as well as for the woven fabric. Tensile and bending strength are presented along the a fully manufactured and operating wind turbine.
