Abstract
A blade includes a plurality of first fibers, wherein each of the plurality of first fibers is angled between about 5° and about 35° with respect to a pitch axis of said blade, and a plurality of second fibers, wherein each of the plurality of second fibers is angled between about 95° and about 125° with respect to the pitch axis of said blade.
Claims22
A blade comprising:
- a plurality of first fibers, wherein each of said plurality of first fibers is angled between about 5° and about 35° with respect to a pitch axis of said blade;
- and
- a plurality of second fibers, wherein each of said plurality of second fibers is angled between about 95° and about 125° with respect to the pitch axis of said blade.
A wind turbine comprising a rotor having a hub and at least one blade extending outwardly from the hub, said blade comprising:
- a plurality of first fibers, wherein each of said plurality of first fibers is angled between about 5° and about 35° with respect to a pitch axis of said blade;
- and
- a plurality of second fibers, wherein each of said plurality of second fibers is angled between about 95° and about 125° with respect to the pitch axis of said blade.
A method for fabricating a blade using a mold having a shape corresponding to a predetermined shape of the blade, said method comprising:
- laying a plurality of first fibers in the mold such that each of the plurality of first fibers is angled between about 5° and about 35° with respect to a pitch axis of the predetermined shape of the blade;
- and
- laying a plurality of second fibers in the mold such that each of the plurality of second fibers is angled between about 95° and about 125° with respect to the pitch axis of the blade.
