Patent number: 10155348Abstract: A material preparation device is provided. The material preparation device includes a bias-ply assembly, a feedstock assembly and an application head. The bias-ply assembly is configured to pass a bias-ply backing material along a first path. The feedstock assembly is configured to pass a feedstock along a second path that crosses the first path at a select angle. The feedstock includes resin pre-impregnated fiber-reinforced material (pre-preg) having the fibers at a first orientation relative to an edge of the feedstock. The application head is configured to transfer the pre-preg from the feedstock to the bias-ply backing material at a location where the first path crosses the second path to form a bias-ply with the fibers of the pre-preg having a second, different orientation relative to an edge of the formed bias-ply.Type: GrantFiled: April 25, 2016Date of Patent: December 18, 2018Assignee: Northrop Grumman Innovation Systems, Inc.Inventors: Jason K. Slack, Christopher J. Madsen, Don C. Jones, Vernon M. Benson, Peter G.

Patent number: 7820092Abstract: Methods of forming an elongated composite structural member are provided. One method includes, providing a substantially elongated mandrel having an exterior surface exhibiting a desired geometry. Laying up a first ply of preimpregnated fiber reinforced material over the mandrel. Applying a force to the first ply to establish a desired amount of tension within the first ply and then pressing the first ply onto the mandrel in a conformal manner. This includes passing at least one roller over the mandrel and the first ply while maintaining the desired amount of tension within the first ply. The at least one roller is at least partially complementary in shape with the mandrel.Type: GrantFiled: November 25, 2008Date of Patent: October 26, 2010Assignee: Alliant Techsystems Inc.Inventors: Vernon M. Benson, Jason K. Slack, Todd A. Rosevear, James L. Harvey, Mark Roman, Timothy Olschewski

Patent number: 7767128Abstract: Method of forming a curved composite structure are provided. In one embodiment, the method includes contacting at least one ply of preimpregnated material on a first surface of a curved mandrel. The first surface of the mandrel has a first radius of curvature. The mandrel further has at least one second surface that has a second radius of curvature. A tension gradient is introduced on the ply adjacent to the first radius of curvature and the ply is then pressed over the curved mandrel to form the curved composite structure.Type: GrantFiled: November 25, 2008Date of Patent: August 3, 2010Assignee: Alliant Techsystems Inc.Inventors: Vernon M.
