METHODS FOR MANUFACTURING SPAR CAPS FOR WIND TURBINE ROTOR BLADES USING THERMOPLASTIC-BASED COMPOSITE PLATES

摘要

In one aspect, a method for manufacturing a spar cap for a wind turbine rotor blade may generally include stacking a plurality of plates together to form a plate assembly, wherein each of the plates is formed from a fiber-reinforced composite including a plurality of fibers surrounded by a thermoplastic resin material. The method may also include positioning the plate assembly relative to a mold defining a mold surface, wherein the mold surface is shaped so as to correspond to at least one blade parameter of the wind turbine rotor blade. In addition, the method may include applying pressure to the plate assembly via the mold such that at least a portion of the plate assembly conforms to the shape of the mold surface.

1. A method for manufacturing a spar cap for a wind turbine rotor blade, the method comprising:
stacking a plurality of plates one on top of the other to form a plate assembly, each of the plurality of plates being formed from a continuous fiber-reinforced composite including a plurality of fibers surrounded by a thermoplastic resin material; positioning the plate assembly relative to a mold defining a mold surface, the mold surface being shaped so as to correspond to at least one blade parameter of the wind turbine rotor blade; applying pressure to the plate assembly via the mold such that at least a portion of the plate assembly conforms to the shape of the mold surface.
