Patent number: 10239289Abstract: A composite assembly that can be cured to form a multi-component composite structure which does not have micro cracks along the boundaries between the various components. The composite assembly includes a structural component and a moldable component wherein the coefficients of thermal expansion of the structural component and the moldable component at the interface or boundary between the two components are such that micro cracks do not form along the interface when the composite assembly is cured to form the multi-component composite structure.Type: GrantFiled: April 12, 2013Date of Patent: March 26, 2019Assignee: HEXCEL CORPORATIONInventor: Bruno Boursier

Patent number: 9724854Abstract: Preforms for use in molding composite parts are made directly from composite chips that are composed of fibers and an uncured thermosetting resin. Cold composite chips are formed into a stream of non-agglomerating chips that is used to fill the cavity of a preform tool. The non-agglomerating chips flow into the preform tool cavity to form a population of non-cohesive composite chips. The non-cohesive composite chips are then heated to form a preform made up of a consolidated population of cohesive composite chips in which the non-sticky uncured thermosetting resin of the non-cohesive chips has been converted to a sticky uncured thermosetting resin.Type: GrantFiled: May 13, 2015Date of Patent: August 8, 2017Assignee: Hexcel Composites LimitedInventor: Bruno Boursier

Patent number: 9393745Abstract: A load-bearing composite structure for connection to a support body or structure. The load-bearing structure includes a load-bearing element that is made up of continuous reinforcing fibers and a resin matrix. The load-bearing element has an attachment portion for connection to the support body. The load-bearing composite structure further includes a connection element that is formed using a molding material which is composed of discontinuous fibers and a resin matrix. The molding material is molded over the surface of the attachment portion of the load-bearing element.Type: GrantFiled: May 15, 2012Date of Patent: July 19, 2016Assignee: Hexcel CorporationInventor: Bruno Boursier

Publication number: 20150355111Abstract: Tracking or tracing of both the global and local movements of unidirectional discontinuous fiber composite (UD-DFC) chips during compression molding of UD-DFC molding compound. The tracking capability is provided by including tracer chips in the UD-DFC molding compound. The tracer chips include a resin matrix and at least one unidirectional carbon tow which is made up of a plurality of carbon filaments. The tracer chip further includes a unidirectional tracer yarn which is made up of a plurality of unidirectional filaments that are detectable by x-ray or other radiation-based scanning technique.Type: ApplicationFiled: June 9, 2014Publication date: December 10, 2015Applicant: HEXCEL CORPORATIONInventor: Bruno Boursier

Publication number: 20140377556Abstract: A method for making a discontinuous fiber molding compound from carbon fiber tow. The method involves using remnants of carbon fiber tows from spent carbon fiber spools. The remnants are chopped into pieces to form an assembly of chopped carbon fiber tows that are from 1 cm to 10 cm long. The chopped carbon fiber tows are then mixed with a powdered resin to form a blend of chopped carbon fiber tows and powdered resin. The blend is heated to soften/melt the particles of resin and then cooled to form a discontinuous fiber molding compound.Type: ApplicationFiled: June 25, 2013Publication date: December 25, 2014Inventor: Bruno Boursier

Patent number: 8864070Abstract: An assembly that includes a first part composed of a fibrous structure that includes fibers and a cured resin matrix. The fibrous structure has at least one surface and a layer that is located on the surface. The layer includes a discontinuous fiber composite that is composed of randomly oriented short fibers and a cured resin matrix wherein the layer has been machined to provide a machined surface. The assembly also includes a second part that is attached to the first part. The second part includes at least one surface that fits against the machined surface on the first part.Type: GrantFiled: August 31, 2011Date of Patent: October 21, 2014Assignee: Hexcel CorporationInventor: Bruno Boursier

Patent number: 8734925Abstract: Composite pre-forms are molded at high pressure to form composite parts that can be used in place of metal-based high performance parts, such as the outlet guide vanes found in turbofan jet engines. The composite pre-forms include two different fiber orientations that are co-molded in a resin matrix at high pressures to provide composite outlet guide vanes and other high performance parts. Chambers within the composite part are optionally formed during molding of the pre-form at high pressures.Type: GrantFiled: October 19, 2011Date of Patent: May 27, 2014Assignee: Hexcel CorporationInventors: Matthew Kweder, Bruno Boursier
