Abstract
A turbomachine part includes a central core which includes a first face and a second face opposite the first face, wherein the central core is surrounded firstly by a first external skin made of a composite material with a first fibrous reinforcement woven according to a three-dimensional weaving located on the first face of the central core, and secondly by a second external skin made of a composite material with a second fibrous reinforcement woven according to a three-dimensional weaving located on the second face of the central core.
Claims13
A turbomachine part comprising:
- a central core made of a rigid cellular material, which comprises a first face and a second face opposite the first face, wherein the central core is free of composite material comprising a fibrous reinforcement woven according to a three-dimensional weaving densified by a matrix,
- a first external skin made of a composite material with a first fibrous reinforcement woven according to a three-dimensional weaving, the first fibrous reinforcement covering the first face of the central core,
- a second external skin made of a composite material with a second fibrous reinforcement woven according to a three-dimensional weaving, the second fibrous reinforcement covering the second face of the central core,
- wherein the first fibrous reinforcement of the first external skin and the second fibrous reinforcement of the second external skin differ in at least one of a weaving pattern, a strand size, a number of woven layers, or a warp-to-weft ratio such that the first and second external skins are structurally distinct from each other.
A turbomachine part comprising a central core made of a rigid cellular material, which comprises a first face and a second face opposite the first face, wherein the central core is free of composite material comprising a fibrous reinforcement woven according to a three-dimensional weaving densified by a matrix, and wherein a first face of the central core is covered by a first external skin made of a composite material with a first fibrous reinforcement woven according to a three-dimensional weaving, and wherein a second face of the central core is covered by a second external skin made of a composite material with a second fibrous reinforcement woven according to a three-dimensional weaving, wherein the first and second external skins are distinct from each other, wherein the first fibrous reinforcement and the second fibrous reinforcement have a different weaving pattern.
A turbomachine part comprising a central core made of a rigid cellular material, which comprises a first face and a second face opposite the first face, wherein the central core is free of composite material comprising a fibrous reinforcement woven according to a three-dimensional weaving densified by a matrix, and wherein a first face of the central core is covered by a first external skin made of a composite material with a first fibrous reinforcement woven according to a three-dimensional weaving, and wherein a second face of the central core is covered by a second external skin made of a composite material with a second fibrous reinforcement woven according to a three-dimensional weaving, wherein the first and second external skins are distinct from each other, wherein the first fibrous reinforcement and the second fibrous reinforcement have a different strand size.
A turbomachine part comprising a central core made of a rigid cellular material, which comprises a first face and a second face opposite the first face, wherein the central core is free of composite material comprising a fibrous reinforcement woven according to a three-dimensional weaving densified by a matrix, and wherein a first face of the central core is covered by a first external skin made of a composite material with a first fibrous reinforcement woven according to a three-dimensional weaving, and wherein a second face of the central core is covered by a second external skin made of a composite material with a second fibrous reinforcement woven according to a three-dimensional weaving, wherein the first and second external skins are distinct from each other, wherein the first fibrous reinforcement and the second fibrous reinforcement have a different number of layers.
