Determination of structural properties of glass/polyester composite for 10 kw wind turbine blades

Abstract

The aim of this paper is to determine the optimal composite material structure for 10 kW wind turbine blades. For this purpose four different sets of specimens of laminated glass/polyester composite material plates in ANSYS Parametric Design Language (APDL) were modelled. Test pieces were subjected to stretching with a force of 10, 20 and 40 kN. According to obtained results the laminate with the required properties was determined. Further, to verify the accuracy of composite materials data input into (APDL) the specimens with high resistance properties will be manufactured and tested at a testing machine. These data will be necessary for FEM analysis of the wind turbine blade.
