WIND TURBINE ROTOR BLADE SHELL WITH VARYING FIBER TYPES

Abstract:

A rotor blade for a wind turbine includes at least one blade segment with at least one shell member defining an airfoil surface. The shell member(s) includes a sandwich panel configuration having one or more inner skin layers, a core material, and one or more outer skin layers. The outer skin layer(s) includes one or more first fibers, whereas the inner skin layer(s) includes one or more different second fibers. Further, the first fiber(s) of the outer skin layer(s) have a higher elastic modulus than the second fiber(s) of the inner skin layer(s).
