Patent number: 9056415Abstract: A forming device and a method of manufacture of a fillet of plastic for aircraft assemblies. The fillet has a pre-determined profile for filling a cavity of a structural element. The fillet is formed using a former of a forming device. The method includes applying at least one blank of a base material of plastic between at least two opposed press beds of the former and at least one of the press beds including an elongated groove. At least one press bed is towards another press bed, until the press beds are in position for completed compression of the fillet. Each groove for forming of the fillet generates a fillet in correspondence with the pre-determined profile. The press beds are separated from each other for releasing the formed fillet. The formed fillet is removed from the former. The formed fillet is applied in the cavity.Type: GrantFiled: August 24, 2006Date of Patent: June 16, 2015Assignee: SAAB ABInventors: Anders Westerdahl, Ingemar Turesson, Eva Andersson, Per Linnerstedt

Patent number: 8871126Abstract: A method for producing an object of composite material comprising the steps of: placing one or several prepregs on a plane surface, forming a fiber stack; lifting over the fiber stack to a molding tool; downforming the fiber stack; curing the downformed fiber stack; where the method also comprises the step of: orienting the fiber directions so that all fibers, when the fiber stack is lifted over to the molding tool, will cross an edge of the molding tool only once.Type: GrantFiled: October 4, 2006Date of Patent: October 28, 2014Assignee: Saab ABInventors: Max Krogager, Mikael Petersson, Björn Weidmann, Ingemar Turesson, Anders Westerdahl, Jan Vaara

Patent number: 8632710Abstract: The present invention relates to a method for the manufacture of a composite article comprising a composite plate (1) and at least one fitting (4). The method is characterized by the steps of arranging at least one former on said composite plate (1), arranging at least one fitting (4) on said composite plate (1), producing a lay-up by applying a composite material layer (9) least partly covering an external surface of the former and of the fitting, and curing the layup in a curing process. After curing, said composite material layer (9) forms the walls of a stiffener and at least partly encloses the fitting so as to support it in a predetermined position.Type: GrantFiled: August 16, 2006Date of Patent: January 21, 2014Assignee: SAAB ABInventors: Mikael Petersson, Björn Weidmann, Max Krogager, Ingemar Turesson

Patent number: 8287790Abstract: A method for manufacturing a hollow load-bearing beam structure of fiber-reinforced composite material. The method includes preparing a first lay-up of a first plurality of layers, and a second lay-up of a second plurality of layers. The first and second lay-ups are positioned on different sides of a mandrel and formed to a beam structure by bending the lay-ups against the mandrel, such that the side edges of the respective layers of the first and second lay-ups are arranged as offset butt joints in the circumferential direction of the formed beam structure.Type: GrantFiled: October 9, 2008Date of Patent: October 16, 2012Assignee: SAAB ABInventors: Anders Westerdahl, Ingemar Turesson, Jan-Erik Lindbäck, Mats Folkesson

Patent number: 7968041Abstract: A method and a tool component for forming in an article of fiber-reinforced composite material at least one locally placed, sharply curved portion. A separate, substantially rigid pressure-transferring element configured with a profile corresponding to the at least one curved portion is placed over the laminate at the location of the at least one locally placed, sharply curved portion of the mold surface. A flexible membrane placed over the laminate and over outer, separated surfaces of the pressure-transferring element is evacuated to depress the laminate to fully conform to the shape of the mold surface.Type: GrantFiled: September 26, 2008Date of Patent: June 28, 2011Assignee: SAAB ABInventors: Anders Westerdahl, Ingemar Turesson
