Patent number: 8465612Abstract: In this manufacturing method, a tubular body 18 having a rib 16 provided therein is obtained. The manufacturing method includes the steps of: preparing a mandrel 2 divided into two or more divided bodies d1 along a longitudinal direction of the mandrel 2; winding a prepreg r1 for a rib around at least one of the divided bodies d1; combining all the divided bodies d1 to obtain a first intermediate body 10 after the step of winding the prepreg r1 for the rib; winding a prepreg g1 for the outer peripheral part around an outside of the first intermediate body 10 to obtain a second intermediate body; heating the second intermediate body to obtain a cured laminate; and extracting the mandrel 2 from the cured laminate. Preferably, the mandrel is equally divided in a circumferential direction. Preferably, a winding start end part t2 of the prepreg r1 for the rib and a winding finish end part t1 thereof overlap with each other.Type: GrantFiled: September 24, 2010Date of Patent: June 18, 2013Assignee: SRI Sports LimitedInventor: Tomio Kumamoto

Patent number: 8414724Abstract: A structural member such as a strut includes a composite material tube having metal end fittings that are attached to the tube by co-bonded, double shear joints. The double shear bond joint construction reduces the residual stress on the bonds that result from mismatch of the coefficients of thermal expansion of the composite tube and the metal end fittings. The ends of the fittings that are bonded to the tube may include a stepped profile that functions to limit the peak stresses in the bonds.Type: GrantFiled: December 2, 2006Date of Patent: April 9, 2013Assignee: The Boeing CompanyInventor: James R.

Patent number: 8398801Abstract: A composite mandrel includes a filament-wound composite tube, and composite material molded over the filament-wound composite tube. For example, the composite material includes chopped fibers and a matrix of thermoset resin. The chopped fibers are arranged in layers upon the filament-wound composite tube, and the chopped fibers in each of the layers are randomly oriented along first and second orthogonal directions in each of the layers. The composite material includes at least one sheet of the composite material wound over the filament-wound tube, and at least one strip of the composite material wound over the sheet of the composite material and forming a head on the composite mandrel. An internal cavity of the filament-wound composite tube may provide a lumen for the composite mandrel. The internal cavity may be threaded to receive a removable bridge plug.Type: GrantFiled: July 29, 2011Date of Patent: March 19, 2013Assignee: Oil States Industries, Inc.Inventors: James Barlow, Joel Barlow

Publication number: 20130034676Abstract: An adhesive stack may comprise a shear layer positioned between two adhesive layers, wherein the shear layer is designed to fail upon application of a deliberate and appropriate shear force and before the failure of the adhesive layers. The adhesive stack may aid in securing components within an electronic device to prevent movement of the component when the device is dropped, hit, or bumped. The adhesive stack may occupy minimal space within the device, and reduce the cost of securing the component within the device's interior. The adhesive stack may allow for replacement of the component by an authorized person applying an appropriate and deliberate force. The adhesive stack may aid in identifying components replaced by an unauthorized person.Type: ApplicationFiled: August 4, 2011Publication date: February 7, 2013Applicant: Apple Inc.Inventor: Matthew P.
