Title:
How to make a curved honeycomb structure made of composite material
Document Type and Number:
Japanese Patent JP6366609
Kind Code:
B2
Abstract:
A method of fabricating a curved cellular structure includes making an expandable fiber structure by multilayer weaving between layers of warp yarns and layers of weft yarns, the structure having zones of non-interlinking extending in the thickness of the structure, the non-interlinking zones spaced apart from one another by portions of interlinking between layers of weft yarns, the portions of interlinking offset by one or more weft yarns in a direction parallel to the direction of the layers of weft yarns between each series of these planes; impregnating the fiber structure with a resin; expanding the fiber structure on support tooling to form a cell in the fiber structure at each zone of non-interlinking, the tooling also presenting a curved shape corresponding to the shape of the cellular structure that is to be fabricated; and polymerizing the resin of the fiber structure to form a curved cellular structure.
