Patent number: 9610756Abstract: A composite material made of multiple filament bands is disclosed. The filament bands are wound to create a composite material. The filament bands may be impregnated with a solid or semi-solid resin. The filament bands are wound in multiple orientations to form a sheet of composite material. Additionally, the composite material may be made to have a varying number of layer and fiber orientations throughout the sheet of composite material. In another embodiment, a composite component requiring multiple layers and fiber orientations may be substantially manufactured during a filament winding process.Type: GrantFiled: February 25, 2013Date of Patent: April 4, 2017Assignee: ROCKY MOUNTAIN COMPOSITES, INC.Inventors: Larry J. Ashton, Craig B. Simpson, Rex W. Kay, Troy L. White, Mike Glen Allman

Patent number: 9140519Abstract: A light weight stiffened gun stock is disclosed herein. The gun stock utilizes structural members oriented in a grid pattern resulting in a high strength-to-weight ratio. The grid pattern can be an isogrid, orthogrid, hoop-grid pattern, or a combination thereof. The structural members define the form of the gunstock, and provide recoil absorption to reduce the amount of recoil experienced by the shooter.Type: GrantFiled: March 20, 2014Date of Patent: September 22, 2015Inventor: Craig B. Simpson

Patent number: 8042315Abstract: A reinforced panel, made of a composite material, includes a single base layer. A first plurality of mutually parallel ridges is affixed to the surface of the base layer. A second plurality of mutually parallel ridges is also affixed to the surface of the base layer, but oriented transverse to the first plurality. Structurally, the ridges and the base layer are co-cured to create an integral, continuous structure that provides stiffness and rigidity to the panel.Type: GrantFiled: September 14, 2007Date of Patent: October 25, 2011Assignee: Spectrum Aeronautical, LLCInventors: Larry J. Ashton, Michael G. Allman, Troy L. White, Craig B. Simpson, Benko S. Ta'ala

Patent number: 7681835Abstract: A single piece co-cured composite wing is disclosed. The wing has a flying surface and structural members. In one embodiment the structural members may be a plurality of spars. The spars may have various shapes to increase the buckling strength. The spars may be wave shaped, such as a sinusoidal shape. The flying surface and the structural members are co-cured in order to form a single piece, integral wing structure. A process for manufacturing a single piece co-cured wing is also disclosed. The process may include laying out composite sheets for the flying surface of the wing. Then, the composite material of the spars is arranged around a plurality of pressurizable forms. Finally, the composite material is cured in a clamshell frame. A single piece co-cured composite structure is also disclosed that includes an outer skin, and inner skin, a frame, and a stringer.Type: GrantFiled: September 23, 2005Date of Patent: March 23, 2010Assignee: Rocky Mountain Composites, Inc.Inventors: Craig B. Simpson, Larry J. Ashton, Mike G. Allman, Steven T. Tuttle

Patent number: 7216832Abstract: A method for manufacturing a composite structure is disclosed herein. The process uses a frame and selectively pressurizable forms. The forms define the interior members of the composite structure and frames define the exterior surface of the composite structure. Composite material is wrapped around the forms and the forms and composite material are placed in the frame. Selective forms are then pressurized and the composite material is co-cured together. A single piece co-cured fuselage incorporating a plurality of stiffeners is also disclosed in the application. The stiffeners are co-cured to the fuselage and may be in various patterns. The patterns may include an iso-grid pattern, and ortho-grid pattern, and a hoop-grid pattern.Type: GrantFiled: December 1, 2004Date of Patent: May 15, 2007Assignee: Rocky Mountain Composites, Inc.Inventors: Craig B.
