ABSTRACT
Low-noise wind turbine blades are being manufactured with hybrid ¤berglass-reinforced materials that are capable of bearing directional loads and are used in the construction of wind turbine blade parts or entire sections. The use of such materials in—uences the air —ow over them in such a way that the resulting boundary-layer turbulence is damped in a controlled way, thus weakening the noise-scattering mechanism at the trailing edge, and the scattered acoustic waves are absorbed and attenuated by the material acting as an acoustic liner.
