Patent number: 11465371Abstract: Grid structure, such as a lattice or grid-stiffened structure and a process of manufacturing such a grid structure. Fiber material is laid up on a base tool to form intersecting ribs defining a grid with a plurality of cavities. In the same step fiber material is laid to form one or more; local substructures. Blocks are placed, at the positions of the cavities. The fiber material of the ribs and. the local substructures is impregnated with a resin. Optionally, one or more layers of fiber material are placed on the base tool and/or over the ribs and the blocks to form an outer skin. The ribs, the local substructure and optionally the outer skin jointly consolidated to form, the grid, structure.Type: GrantFiled: November 30, 2016Date of Patent: October 11, 2022Assignee: ATG EUROPE B.V.Inventors: Leonid Pavlov, Ivar Te Kloeze, Bart Jozef Robbert Smeets, Sahak Menzo Simonian
