Abstract
A wind blade spar cap laminate repair for wind turbine rotor blades, a repair kit to repair spar cap laminate damage, and a method of repairing damage on wind turbine rotor blades is provided. The wind blade spar cap laminate repair includes a prepared surface, an adhesive region disposed on the prepared surface, and a repair disposed on the adhesive region, wherein the adhesive region sufficiently bonds the repair to the prepared surface to substantially match the mechanical properties of the bulk of the wind turbine rotor blade.
Claims18
A patched wind turbine rotor blade comprising,
- (a) a prepared surface, the prepared surface including a scarf area to remove damage from the wind turbine rotor blade, the scarf area including a plurality of stepped portions;
- (b) an adhesive region disposed on the prepared surface, wherein the adhesive region comprises at least one composite fabric ply and a matrix material, wherein the at least one fabric ply of the adhesive region is applied parallel over the entire length of the scarf area;
- and
- (c) a repair disposed on the adhesive region, wherein the adhesive region sufficiently bonds the repair to the prepared surface to substantially match the mechanical properties of the bulk of the turbine rotor blade.
A method of repairing damage on wind turbine rotor blades, comprising:
- (a) preparing a surface on the wind turbine rotor blade, wherein preparing the surface includes removing damage from the wind turbine rotor blade to provide a scarf area, wherein the scarf area includes a plurality of stepped portions;
- (b) applying an adhesive region to the prepared surface, wherein the adhesive region comprises at least one composite fabric ply and a matrix material, wherein the at least one fabric ply of the adhesive region is applied parallel over the entire length of the scarf area;
- and
- (c) applying a repair to the adhesive region, wherein the adhesive region sufficiently bonds the repair to the prepared surface to substantially match the mechanical properties of the bulk of the blade.
