Abstract

Results of experimental investigations into a unidirectional composite of basalt fibers and epoxy resin used as part of high-voltage electric wires are presented. Tensile tests of BFRP specimens previously held wrapped around a transportation drum during 10 h were carried out. The influence of the keeping time of the BFRP core in the composition of a high-voltage electric wire on drums of diameter 385 mm on the elastic, strength and deformation properties of the basalt plastic was evaluated. Tensile, three-point bending and torsion tests on the plastic with different static loads were carried out, and the corresponding deformation diagrams were obtained. The maximum torsion angle of BFRP specimens as a function of the axial load is determined. The results obtained can help one to analyze the operating modes of BFRP core in high-voltage electric wires and to get new data for their strength calculations.
