A wind turbine blade includes a laminated structure having an outer shell (1) having a shape of the blade, an upwind-side reinforcing section (4a) which reinforces a upwind-side part of the blade in the outer shell 1 and a downwind-side reinforcing section 4b which reinforces a downwind-side part of
A wind turbine blade includes a laminated structure having an outer shell (1) having a shape of the blade, an upwind-side reinforcing section (4a) which reinforces a upwind-side part of the blade in the outer shell 1 and a downwind-side reinforcing section 4b which reinforces a downwind-side part of the blade in the outer shell 1. The outer shell 1 includes a first multidirectional material, a first unidirectional reinforcing material 12 and another multidirectional material 11 which are layered. The upwind-side reinforcing section 4a includes another unidirectional reinforcing material 12 provided between the first unidirectional reinforcing material 12 and another multidirectional material 11. The downwind-side reinforcing section 4b includes yet another unidirectional reinforcing material provided between the unidirectional reinforcing material 12 and the multidirectional material 11. The outer shell 1 includes a first core member 13 respectively provided between the upwind-side reinforcing section 4a and the downwind-side reinforcing section 4b on a leading edge side, and between the upwind-side reinforcing section 4a and the downwind-side reinforcing section 4b on a trailing edge side.

1. A wind turbine blade comprising a laminated structure which comprises an outer shell having a shape of the blade, an upwind-side reinforcing section which reinforces a upwind-side part of the blade in the outer shell and a downwind-side reinforcing section which reinforces a downwind-side part of the blade in the outer shell, wherein the outer shell comprises a first multidirectional material, a first unidirectional reinforcing material and a second multidirectional material which are layered,wherein the upwind-side reinforcing section comprises a second unidirectional reinforcing material provided between the first unidirectional reinforcing material and the second multidirectional material,wherein the downwind-side reinforcing section comprises a third unidirectional reinforcing material provided between the first unidirectional reinforcing material and the second multidirectional material,wherein the outer shell comprises a first core member,respectively provided between the upwind-side reinforcing section and the downwind-side reinforcing section on a leading edge side, and between the upwind-side reinforcing section and the downwind-side reinforcing section on a trailing edge side, andwherein the blade comprises the laminated structure from a root of the blade to vicinity of a maximum chord location at which a chord is maximum and the blade comprises other laminated structure from the maximum chord location to a tip of the blade. 2. The wind turbine blade according to claim 1, wherein the laminated structure further comprises a trailing edge reinforcing section which reinforces a trailing edge part of the blade in the outer shell,wherein the trailing edge reinforcing section comprises a fourth unidirectional reinforcing material arranged between the first unidirectional reinforcing material and the second multidirectional material, andwherein the outer shell comprises the first core member respectively provided between the upwind-side reinforcing section and the downwind-side reinforcing section on the leading edge side, between the upwind-side reinforcing section and the trailing edge reinforcing section, and between the downwind-side reinforcing section and the trailing edge reinforcing section. 3. The wind turbine blade according to claim 1, wherein the outer shell comprises a fifth unidirectional reinforcing material which is provided on an inner side of the second multidirectional material so as to be layered on the second multidirectional material. 4. The wind turbine blade according to claim 1, wherein said other laminated structure comprises other outer shell having a shape of the blade, other upwind-side reinforcing section which reinforces the upwind-side part of the blade in said other outer shell, other downwind-side reinforcing section which reinforces the downwind-side part of the blade in said other outer shell, other leading edge reinforcing section which reinforces the leading edge part of the blade in said other outer shell and other trailing edge reinforcing section which reinforces the trailing edge part of the blade in said other outer shell,wherein said other outer shell comprises the first multidirectional material and the second multidirectional material which are layered,wherein said other upwind-side reinforcing section comprises a sixth unidirectional reinforcing material provided between the first multidirectional material and the second multidirectional material,wherein said other downwind-side reinforcing section comprises a seventh unidirectional reinforcing material provided between the first multidirectional material and the second multidirectional material,wherein said other leading edge reinforcing section comprises a eighth unidirectional reinforcing material provided between the first multidirectional material and the second multidirectional member,wherein said other trailing edge reinforcing section comprises a ninth unidirectional reinforcing material between the first multidirectional material and the second multidirectional material, andwherein said other outer shell comprises a second core member respectively provided between said other upwind-side reinforcing section and said other leading edge reinforcing section, between said other upwind-side reinforcing section and said other trailing edge reinforcing section, between said other downwind-side reinforcing section and said other leading edge reinforcing section, and between said other downwind-side reinforcing section and said other trailing edge reinforcing section. 5. A wind turbine generator comprising a rotor head supported rotatably with respect to a nacelle and the wind turbine blade according to claim 1 which is mounted on a rotor head, wherein a wind turbine rotor is constituted of the rotor head and the wind turbine blade,wherein the turbine rotor is rotated by a wind force and a rotation energy of the turbine rotor is converted to power generation energy.
