Patent application numberDescriptionPublished
20090025448Method and apparatus for manufacture of a profile element - A method and an apparatus for manufacturing of a profile element including a web portion, a first and second flange portion, which extend from the web portion and are disposed essentially opposite each other. The method includes folding a blank of composite material about a first and second flange forming surface of a forming tool. The method includes setting at least one flange forming surface of a forming tool a distance from another flange forming surface greater than a desired distance between inner surfaces of the flange portions of a finished profile element. The folded blank is cured and a gradual decrease of the distance between the flange forming surfaces is simultaneously controlled. The cured profile element is removed from the forming tool.01-29-2009
20090025865Method and apparatus for manufacturing of a wing spar profile element - A method and an apparatus for manufacture of an elongated beam profile element including a recess configured to accommodate a support element. The method includes forming the blank into the web portion with at least one first protrusion formed to extend across the web portion and to protrude outward from the web portion's outer surface; and into the first flange portion with at least one second protrusion formed to extend across the first flange portion and to protrude inward from the first flange portion's inner surface, wherein this second protrusion merges into the first protrusion and constitutes the recess for accommodating the support element under a wing.01-29-2009
20090057948Method and apparatus for manufacturing a curved elongated structural element - A method and an apparatus for manufacturing of a curved elongated structural element of composite material. The curved elongated structural element includes a first elongated portion and a second elongated portion in an angled relation. A substantially flat blank of composite material including a first and second elongated edge is provided. The blank is folded over a first portion forming surface and a second portion forming surface of a forming tool's flexible tool body for forming the first elongated portion and the second elongated portion. The forming tool's tool body is bent such that its bending moment center prevails essentially adjacent the first portion forming surface.03-05-2009
20090091063METHOD AND DEVICE FOR SHAPING OF COMPOSITE MATERIAL - A method and device for shaping of an article of composite material. The method includes arranging a blank of composite material on a top surface of a forming tool. A portion of the blank is arranged to protrude outside the top surface of the tool. At least one support is arranged in contact with an underside of the protruding portion of the blank. An air-tight foil is arranged over the arrangement. The air-tight foil is forced towards the blank. The support is lowered until the blank is shaped over the tool. The support is stopped and/or removed. The device includes a tool including a top surface and side surface for shaping at least one blank of composite material into an article having a predetermined profile; and a air-tight foil. The device further includes at least one support arranged to be in supporting contact with the underside of the protruding part of the blank.04-09-2009
20090110836METHOD OF FORMING A COMPOSITE STRUCTURE - The present invention relates to a method of manufacturing a composite structure (04-30-2009
20090152775METHOD AND APPARATUS FOR MANUFACTURING OF AN ARTICLE INCLUDING AN EMPTY SPACE - A tool assembly including a male tool including an inner shape tool including a bag having a connection connectable to a depressurization source for providing a vacuum in the bag such that beads therein form a body of firm cohesion providing the inner shape tool rigid. The male tool further includes a flexible, hollow curing support arranged around the rigid inner shape tool, the inner shape tool is arranged to be removable from the flexible, hollow curing support by rupturing the vacuum.06-18-2009
20100148005CURVED BEAM OF FIBER COMPOSITE MATERIAL - A curved beam of fiber composite material. The beam includes a first flange curved in a longitudinal direction, a second flange curved in a longitudinal direction and having a greater longitudinal extent than the first flange, and a web curved in a longitudinal direction and extending between the first flange and the second flange. The beam includes a fiber composite laminate including layers of fibers having different fiber directions, wherein a fiber density per unit of area of the second flange is lower than a fiber density per unit of area of the first flange, and wherein the first flange, the second flange and the web are seamless, continuous, and unfolded in a longitudinal direction.06-17-2010
20120003347METHOD AND DEVICE FOR SHAPING OF COMPOSITE MATERIAL - A device for shaping of an article of composite material. The device includes a tool including a top surface and side surface for shaping at least one blank of composite material into an article having a predetermined profile; and a air-tight foil. The device further includes at least one support arranged to be in supporting contact with the underside of the protruding part of the blank.01-05-2012
