Abstract: An erosion resistant aerodynamic fairing for a rotor blade. A fairing body is formed from at least one reinforcing fiber layer set in a cured resin. An erosion resistant pre-form is fixed to an outer surface of the fairing body. The erosion resistant pre-form comprises a thermoplastic film outer layer fused to a fiber substrate. The fiber substrate of the erosion resistant pre-form is impregnated with the cured resin of the fairing body which fixes at the preform to the fairing body.

Abstract: A method of making a root end joint for a wind turbine. A plurality of root segments (10) are formed of a composite material. Each has an arcuate end face (11) which subtends an angle of 90° or less and has a plurality of connection holes (12). The segments are joined together side-by-side to build up the circular profile of the root end. The segments include a proportion of uni-axial to multiaxial fiber which decreases from the arcuate end face towards the opposite end.
