Publication number: 20140252688Abstract: An article of manufacture having an in-molded resistive and/or shielding element and method of making the same are shown and described. In one disclosed method, a resistive and/or shielding element is printed on a film. The film is formed to a desired shape and put in an injection mold. A molten plastic material is introduced into the injection mold to form a rigid structure that retains the film.Type: ApplicationFiled: January 31, 2014Publication date: September 11, 2014Applicant: T-Ink, Inc.Inventors: Ronald H. Haag, Jeffrey R. Engel, William W. Boddie, JR.

Method for joining cured stringers to at least one structural component of an aircraft or spacecraft
Patent number: 8808493Abstract: The invention relates to a method for joining cured stringers to at least one structural component of an aircraft or spacecraft, including placing the stringers onto the at least one structural component, depositing and pressing respective vacuum film strips such that each strip is attached to a pair of stringers and present between the pair of stringers with the use of vacuum sealing means in such a manner that a continuous vacuum arrangement, comprising the covering vacuum films and the vacuum film strips, is formed, and pressurized joining of the stringers to the at least one structural component by means of the continuous vacuum arrangement formed.Type: GrantFiled: July 19, 2011Date of Patent: August 19, 2014Assignee: Airbus Operations GmbHInventors: Peter Sander, Hans Marquardt, Hauke Lengsfeld -
Publication number: 20140225296Abstract: A method of making a sandwich-type, compression-molded, composite component having improved surface appearance is provided. Resin skins and a core of a blank or stack of sandwich materials are heated to a softening temperature of the resin. A compression mold is provided including component-forming, upper and lower dies with opposing molding surfaces cooperating to define a mold cavity. The heated blank or stack is allowed to cool in the mold cavity until inner surfaces of the skins are bonded to top and bottom surfaces of the core to seal core cavities. Air in the sealed cavities urges softened portions of the skins inwardly towards the cavities of the core as the air in the cavities cools. A vacuum is applied at a first outer surface of the blank or stack in the mold cavity sufficient to prevent debossing and improve appearance of the first outer surface.Type: ApplicationFiled: February 8, 2013Publication date: August 14, 2014Applicant: GLOBAL IP HOLDINGS, LLCInventors: Darius J. Preisler, Christopher A. Heikkila
