Patent number: 11560650Abstract: A method of fabricating a fiber structure by multilayer three-dimensional weaving between a plurality of weft yarns and of warp yarns, the fiber structure having at least first and second portions that are adjacent in the warp direction, the first portion presenting, in a direction perpendicular to the warp and weft directions, a thickness greater than the thickness of the second portion, includes making the first portion using a step of three-dimensionally weaving warp and weft layers in which a fiber fabric is formed in the form of a Mock-Leno weave grid in a core of the first portion together with skins at a surface of the first portion, a weave of the skins being modified locally so as to deflect certain warp yarns from said skins and weave them with the fiber fabric in the form of the Mock-Leno weave grid.Type: GrantFiled: April 2, 2021Date of Patent: January 24, 2023Assignees: SAFRAN CERAMICS, ALBANY INTERNATIONAL CORP.Inventors: Marie Lefebvre, François Charleux, Dominique Coupe, Brock Gilbertson, Julie-Anne Bouchet

Patent number: 9604389Abstract: A woven preform for a reinforced composite material, which may be woven flat and folded into shape. The preform has off-axis reinforcement with one or more legs and/or base extending in an off axis or bias (non 0/90 degree) orientation with respect to the warp/weft fibers. One or more legs extend from a base, the base and legs each having at least two layers of warp fibers. The legs may be parallel or angled to each other. The outer ends of the base and/or the legs may have tapers formed from terminating layers of warp fibers in a stepped or angled pattern.Type: GrantFiled: February 17, 2012Date of Patent: March 28, 2017Assignee: Albany Engineered Composites, Inc.Inventors: Brock Gilbertson, Jonathan Goering

Patent number: 9597841Abstract: A fiber structure for reinforcing a composite material part, the structure being woven as a single piece by multilayer weaving between a first plurality of layers of yarns extending in a first direction and a second plurality of layers of yarns extending in a second direction. The second plurality of layers of yarns includes at least one layer of variable-weight yarns, each variable-weight yarn including a separable assembly of individual yarns, each having a determined weight. The fiber structure includes at least one portion of reduced thickness in which the variable-weight yarn presents a weight that is less than the weight that it presents prior to the reduced thickness portion.Type: GrantFiled: December 10, 2012Date of Patent: March 21, 2017Assignee: SNECMAInventors: Bruno Jacques Gerard Dambrine, Dominique Coupe, Jonathan Goering, Brock Gilbertson, Jean-Noel Mahieu

Patent number: 8127802Abstract: A woven preform for a reinforced composite material, which may be woven flat and folded into shape. The preform has a three-dimensional weave architecture with fill fibers woven to provide layer-to-layer interlocking of layers of warp fiber as well as interlocking of fibers within each layer. At least two legs extend from a base, the base and legs each having at least two layers of warp fibers. The legs may be parallel or angled to each other, or may have a variable width clevis in between. The outer ends of the base and/or the legs preferably have tapers formed from terminating layers of warp fibers in a stepped pattern.Type: GrantFiled: October 29, 2008Date of Patent: March 6, 2012Assignee: Albany Engineered Composites, Inc.Inventors: Kenneth Ouellette, Jonathan Goering, Brock Gilbertson
