Abstract
A blade comprises a lightweight core, a composite material disposed on the core, and a skin located on the composite material. The composite material comprises fibers incorporated into a thermoplastic resin matrix in the form of a prepreg sheet or wet layup. The rotor blade may also comprise a front edge member attached along at least a portion of a leading edge of the core, a rear edge member attached along at least a portion of a trailing edge of the core, and a skin located over the core, the front edge member, and the rear edge member. The rotor blade may also comprise a spar extending through the core along a longitudinal axis of the rotor blade, and a skin located over the core and the spar. The edge members and the spars may be fabricated from thermoplastic material.
Claims25
A blade, comprising:
- a core;
- a composite material disposed on the core;
- and
- a skin located on the composite material;
- wherein the composite material comprises fibers incorporated into a thermoplastic resin matrix, and the thermoplastic resin matrix is a material selected from the group consisting of polyethylene terephthalate, polyvinyl chlorides, polyvinylidene chlorides, polyvinyl acetates, polypropylenes, polyethylenes, polystyrenes, polyurethanes, polyphenylene sulfide, and combinations of the foregoing materials.
A rotor blade for a wind turbine, the rotor blade comprising,
- a core;
- a front edge member attached to the core along at least a portion of a leading edge defined by the core;
- a rear edge member attached to the core along at least a portion of a trailing edge defined by the core;
- and
- a skin located over the core, the front edge member, and the rear edge member;
- wherein at least one of the front edge member and the rear edge member comprises a thermoplastic composite material.
A rotor blade for a wind turbine, the rotor blade comprising,
- a core;
- a spar extending through the core along a longitudinal axis of the rotor blade;
