Wind turbine blade and method of fabricating a wind turbine blade |
| 摘要 |
A wind turbine blade (162) and a method of forming a wind turbine blade. The method includes: forming an inner segment (10) of an airfoil, leaving a portion (16) of an inner weave (12) extending from the inner segment; forming an outer segment (18) of the airfoil, leaving a portion (24) of an outer weave (20) extending from the outer segment; overlapping the extending portion of the inner weave with the extending portion of the outer weave; infusing the overlapped extending portions with additional resin; and curing the additional resin to form a monolithic airfoil (160). |

1. A method of forming a wind turbine blade, the method comprising:
forming an inner segment of an airfoil, leaving a portion of an inner skin weave and a portion of an inner spar cap weave extending from the inner segment; forming an outer segment of the airfoil, leaving a portion of an outer skin weave and a portion of an outer spar cap weave extending from the outer segment; overlapping the extending portion of the inner skin weave with the extending portion of the outer skin weave; overlapping the extending portion of the inner spar cap weave with the extending portion of the outer spar cap weave; infusing the overlapped extending portions of the skin weaves and the spar cap weaves with resin in a single operation; and curing the resin to form a monolithic airfoil. |
