Abstract
A wind turbine blade (10) including: a spar cap (18) having first fibers (38) oriented parallel to a longitudinal axis (40) of the blade (10); and a fiber member (50, 52, 54, 56, 58) joined to the spar cap at a joint (30, 32, 34) and having second fibers (80). The second fibers are oriented at a first angle (α, β) relative to the longitudinal axis along portions remote (100, 130) from the joint and are curved toward the longitudinal axis in a harmonizing region (102, 122, 132) proximate the joint.
Claims20
A wind turbine blade comprising:
- a spar cap comprising first fibers oriented parallel to a longitudinal axis of the blade;
- and
- a fiber member joined to the spar cap at a joint and comprising second fibers;
- wherein the second fibers are oriented at a first angle relative to the longitudinal axis along portions remote from the joint and are curved toward the longitudinal axis in a harmonizing region proximate the joint.
1 more element
A wind turbine blade, comprising:
- a first member comprising first fibers;
- a second member comprising second fibers;
- and
- an interface between the first member and the second member;
- wherein the first fibers reorient from an orientation that is not parallel with the second fibers remote from the interface toward being more parallel with the second fibers proximate the interface.
