Publication number: 20170240714Abstract: Process for producing a composite material comprising depositing a prepreg containing a radiation initiated curing agent onto a mould using automated apparatus and applying heat and second source radiation to at least partially cure the prepreg at least simultaneously with the deposition of the prepreg. Also epoxy resin formulations of a mixture of a liquid epoxy resin and a solid or semi-solid epoxy resin containing a photoinitiator are used as the matrix in prepregs which are cured or partially cured by radiation to avoid the need for thermal cure in an oven. The formulation is particularly useful in the production of wind turbine blades especially in an automated process. Additionally an automated tape laying apparatus comprising compaction device, a heat source and a second radiation source.Type: ApplicationFiled: October 21, 2015Publication date: August 24, 2017Inventors: Asher Ahmed, Chris Harrington, Nicholas Verge

Publication number: 20170239894Abstract: Mechanically attaching articles made from composites has problems due to the difference in properties of the composite in the x, y planar direction and the z perpendicular direction, this results in different properties between the composite and the attachment member such as differences in coefficients of thermal expansion which can weaken the joint further leading to differences in moisture uptake which can further reduce the strength and robustness of the joint. The invention relates to the selection of the position of a joint in order to reduce such problems and to operating the moulding process in a way that improves the provision of mechanical attachments such as bolt holes.Type: ApplicationFiled: August 18, 2015Publication date: August 24, 2017Inventors: Denis Granger, Chris Harrington, Asher Ahmed, Joseph Gargiuli

Publication number: 20170226274Abstract: This invention relates to an epoxy resin formulation containing a curative that can be cured at 150° C. to 95% cure in no more than 150 seconds, and can be cured at 120° C. to 95% cure in no more than 4 minutes. This results in a cured resin having a Tg no greater than 140° C. wherein the formulation further contains a mould release agent.Type: ApplicationFiled: September 21, 2015Publication date: August 10, 2017Applicant: Hexcel Composites LimitedInventor: Chris Harrington

Publication number: 20160376399Abstract: (57) Abstract: The present invention concerns a process for the production of wind turbine structures. In the process, a stack of prepregs is located inside a vacuum bag. Each of the prepregs comprises a mixture of fibrous reinforcement and from 20% to 85 wt % of an epoxy resin of EEW 150 to 1500 and containing from 0.5 to 10 wt % of a curing agent. The curing agent comprises a urea curing agent and an imidazole curing agent, and is free of dicyandiamide. The epoxy resin is cured by application of an externally applied temperature in the range 70° C. to 110° C. for a period of from 4 to 8 hours.Type: ApplicationFiled: July 28, 2014Publication date: December 29, 2016Inventors: Philip Hadley, Mark Whiter, Chris Harrington

Patent number: 9328262Abstract: The adhesion between an underlying composite material and its surface finish is increased by including an adhesion promoting layer at the interface where the uncured composite material and the surface finish meet during the lay up of the uncured composite assembly. The adhesion promoting layer includes a cure accelerating agent for the composite material matrix resin.Type: GrantFiled: May 23, 2007Date of Patent: May 3, 2016Assignee: Hexcel Composites LimitedInventor: Chris Harrington
-
Publication number: 20160053060Abstract: A cured or partly cured fiber reinforced sheet material comprising reinforcement fibres and a reinforcement resin material, wherein the reinforcement resin material comprises an epoxy resin having an epoxy equivalent weight in the range of from 50 to 250, preferably from 100 to 200, and an amine hardener, the sheet material comprising a surface structure for spacing the sheet material from adjacent moulding materials.Type: ApplicationFiled: November 20, 2013Publication date: February 25, 2016Applicants: HEXCEL COMPOSITES LIMITED, Hexcel Holding GMBHInventors: Johannes Moser, Philip Hadley, Ben Tipler, Chris Harrington, Nicholas Verge

Patent number: 8404311Abstract: A resin composition that is storable at ambient temperatures. The resin composition forms a cured resin when exposed to a curing agent and heated to a curing temperature that is relatively close to ambient temperature. The resin composition includes a resin component that is composed of a liquid part that is made up of one or more liquid thermosetting resins and a solid part that includes particles of one or more solid thermosetting resins. The liquid part further includes a gelation agent that is present in a sufficient amount to maintain the particles in suspension within the liquid part at ambient temperatures. The viscosity of the resin component changes from a high viscosity state to a low viscosity state when the temperature is increased from ambient temperature to the curing temperature. The high viscosity state is substantially more viscous than the low viscosity state.Type: GrantFiled: November 8, 2011Date of Patent: March 26, 2013Assignee: Hexcel Composites, Ltd.Inventors: Chris Harrington, Philip C.

Patent number: 8304080Abstract: A resin composition that is storable at ambient temperatures. The resin composition forms a cured resin when exposed to a curing agent and heated to a curing temperature that is relatively close to ambient temperature. The resin composition includes a crystalline resin component that is sandwiched between two non-crystalline resin components to provide a zone that is rich in crystalline thermosetting resin. The crystalline thermosetting resin has a melting point that is above ambient temperature, but below the curing temperature. The viscosity of the resin component changes from a high viscosity state to a low viscosity state when the temperature is increased from ambient temperature to the curing temperature.Type: GrantFiled: November 23, 2010Date of Patent: November 6, 2012Assignee: Hexcel Composites Ltd.Inventors: Chris Harrington, Philip C.
