Patent number: 11181011Abstract: A method of fabricating a composite material casing of varying thickness for a gas turbine includes using three-dimensional or multilayer weaving to make a fiber texture in the form of a strip; winding the fiber texture as a plurality of superposed layers onto a mandrel of profile corresponding to the profile of the casing to be fabricated, so as to obtain a fiber preform of shape corresponding to the shape of the casing to be fabricated; and densifying the fiber preform with a matrix. During winding of the fiber texture on the mandrel, a textile strip is interposed between the adjacent turns of the fiber texture, the textile strip presenting a width that is less than the width of the fiber texture and defining a retention zone of the casing.Type: GrantFiled: December 21, 2016Date of Patent: November 23, 2021Assignees: SAFRAN AIRCRAFT ENGINES, SAFRANInventors: Hubert Jean-Marie Fabre, Jérémy Hellot, Antoine Phelippeau, Yann Didier Simon Marchal, Bruno Jacques Gérard Dambrine

Patent number: 9827639Abstract: A method of placing a fastener plate on a structure made of composite material, the structure being obtained by a technique of injecting resin under a vacuum, the technique including placing a fiber preform in a closed mold, injecting a thermosetting resin into the mold, and polymerizing the resin prior to cooling. The method includes mounting a metal fastener plate against a wall of the mold before putting the fiber preform into place, the fastener plate coming into contact with one of faces of the fiber preform while the fiber preform is being put into place in the mold, and the resin becoming deposited between the fastener plate and the fiber preform while the resin is being injected into the mold. The method may be used in particular for fastening equipment on a composite material fan casing of a gas turbine for an aeroengine.Type: GrantFiled: February 1, 2013Date of Patent: November 28, 2017Assignee: SNECMAInventors: Richard Mathon, Antoine Phelippeau

Publication number: 20170198421Abstract: A method of fabricating a textile structure of varying thickness, the method including weaving a fiber texture in the form of a strip and winding the fiber texture under tension onto a mandrel, the fiber texture including a greater-thickness portion presenting greater thickness. During winding of the fiber texture on the mandrel, an interleaving element is interposed between adjacent turns of the fiber texture on the mandrel, the interleaving element extending in the width direction of the fiber texture over a portion of the texture that lies outside the greater-thickness portion. The interleaving element presents, over the portion of the texture situated outside the greater-thickness portion, a thickness that corresponds at least to the difference between the thickness of the greater-thickness portion and the thickness of the portion of the texture situated outside the greater-thickness portion.Type: ApplicationFiled: January 11, 2017Publication date: July 13, 2017Inventors: Jérémy HELLOT, Dominique Marie Christian COUPE, Hubert Jean Marie FABRE, Antoine PHELIPPEAU, Micah Christian GUMMEL
