Braided reinforcement for aircraft fuselage frames and method of producing the same
A method for applying a braided fabric over a mandrel using a braiding apparatus having a central axis and providing braiding yarns drawn toward a braiding point where a braid is formed on the mandrel, the method comprising the steps of advancing the mandrel through the braiding point of the braiding apparatus, determining a current position of the mandrel; and controlling the position of the mandrel transversely to the central axis of the braiding apparatus responsive to the current position such that a center point of a mandrel cross-section passing through the braiding apparatus is coincident with the braiding point.
By the present invention method and apparatus is disclosed whereby a triaxial braided composite reinforcing fabric having axial yarns of varying length may be wrapped about a cylindrical shipping spool without deformation of the braided fabric. A tensioning device is interposed between the braiding tool and shipping or storage spool whereby the individual variable length axial yarns are subjected to constant tensioning. As the braided fabric is wound upon a cylindrical shipping spool, a conformable foam layer is interposed between each layer of braided fabric thereby permitting each axial yarn to seek out its own diameter by compressing the layer of conformable foam upon which it is wrapped.

BRAIDED REINFORCEMENT FOR AIRCRAFT FUSELAGE FRAMES AND METHOD OF PRODUCING THE SAME
A machine and method for applying braid by means of a braiding machine to a mandrel, where the mandrel has a shape that approximates a wheel but has an irregularly varying radius of curvature. The machine includes drive/positioning wheel assemblies that are used to continuously reposition a cross-section of the mandrel relative to the braiding machine such that a center point of cross-section of the mandrel is maintained to be coaxial with a braiding point of the braiding machine as the mandrel (18) is rotationally advanced by the drive/positioning wheel assemblies. Repositioning of the drive/positioning wheel assemblies is controlled by a computer numerical control (CNC) controller, based on information describing one or more radiuses of curvature for sections of the mandrel and a current position of the mandrel relative to the drive/positioning wheel assemblies.
