The composite panel has two outer facing sheets, and a core. Studs are provided on one of the outer facing sheets. The manufacturing process involves forming the panel on a mold by laying down a gel coat (optional), a lower facing sheet (used instead of, or with, the gel coat), the core piece(s), and the top facing layer. This can be done by a lamination process, or preferably is done by laying down fibrous material for the facing sheet(s) and vacuum-infusing it with resin, and curing the panel. The core pieces may either be pre-made, or (if infusion is used) may themselves be made in this process, by infusing them with the resin as well. The studs are preferably of galvanized steel and are secured by means of an adhesive.Type: GrantFiled: August 2, 2012Date of Patent: May 20, 2014Assignee: Crane Composites Inc.Inventors: Robert Hancock, Wenping Zhao

Patent number: 8721956Abstract: A fluid receptacle may include an outer wall defining a periphery of the fluid receptacle, and an inner wall. The inner wall may be connected to the outer wall at certain locations and spaced from the outer wall at other locations providing gaps between the outer wall and the inner wall. In some implementations, the inner wall may be complete or continuous and liquid fuel may be contained within the inner wall. In other implementations, liquid fuel may be received between the inner and outer walls.Type: GrantFiled: March 2, 2011Date of Patent: May 13, 2014Assignee: TI Automotive Technology Center GmbHInventors: Albert J. Boecker, Andreas W. Dobmaier, Alex Ehler, Peter Grauer, Matthias B. Olbrich, Bernd Weber

Publication number: 20140124987Abstract: The invention relates to a method of injection molding a part (1) made of composite material, the method consisting in placing a preform in a mold, in injecting a resin into the mold so as to impregnate the preform, and in unmolding the part (1) after curing the resin, the method being characterized in that it also consists in subjecting the resin and the preform to pressure inside the mold while the resin is curing, e.g. by injecting a gas under pressure into the mold via a plurality of points (2, 4, 5, 6).Type: ApplicationFiled: May 2, 2012Publication date: May 8, 2014Applicant: SNECMAInventors: Thierry Godon, Bruno Jacques Gérard Dambrine, Eduardo Antonio Julian Ruiz, François Trochu

Patent number: 8703039Abstract: A microstructured composite component is provided including structures for carrying out fluid processes. A device is provided for producing microstructured composite components. A method provided includes a first step during which a first film is arranged above a second film between first and second mold parts. The first and/or second mold parts have microstructured cavities to be filled. In a second step, the first and second mold parts are heated in at least one region in which they contact one of the films. An excess pressure is then produced between the first film and the second film to force the first and/or second films into the cavities. In a further step, the first and second mold parts are pressed together by a pressing force. Once the first mold part, the second mold part, the first film and the second film are cooled, they form a microstrutured composite component.Type: GrantFiled: February 24, 2010Date of Patent: April 22, 2014Assignee: Technische Universitat IlmenauInventors: Andreas Schober, Alexander Gross, Joerg Hampl

Patent number: 8696965Abstract: Systems and methods for the fabrication of prepregs possessing enhanced ability for the removal of gases from within prepregs and prepreg layups prior to and/or during at least a portion of consolidation and cure process to form composite structures are disclosed. In certain embodiments, perforations of selected configurations may be introduced into the prepregs prior to, during, and after layup. The perforations provide routes for gases trapped within and between the perforated prepregs and prepreg lay-ups to escape during consolidation and cure process, reducing the residual porosity within the resulting composite. For example, composites having residual porosities less than 10 vol. %, on the basis of the volume of the composite, may be achieved in this manner.Type: GrantFiled: October 16, 2009Date of Patent: April 15, 2014Assignee: Cytec Technology Corp.Inventors: Christopher Lee Bongiovanni, Jack Douglas Boyd

Publication number: 20140083487Abstract: An improved backsheet used in the construction of solar panels is disclosed. A method of manufacturing the backsheet and solar panel comprising the backsheet, including coextrusion processes are also disclosed. Additionally, a photovoltaic solar panel module comprising the backsheet of the invention is disclosed. The backsheet of the instant invention may comprise an exterior layer having inner and outer surfaces, a middle layer, having inner and outer surfaces, and an interior layer having inner and outer surfaces. In one embodiment of the invention, the outer surface of the middle layer may be adjoined to the inner surface of the exterior layer, and the inner surface of the middle layer may be adjoined to the outer surface of the interior layer. The exterior layer, middle layer, and interior layer may be adjoined via a co-extrusion process, thereby eliminating the need for the use of adhesives for bonding the layers of the backsheet together.Type: ApplicationFiled: September 25, 2012Publication date: March 27, 2014Inventors: E.
