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 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.

A mandrel for use as a substrate in the manufacture of woven or braided articles may comprise an inner core of foam; at least a first intermediate layer of carbon fiber-reinforced resin; and an outer layer of glass fiber-reinforced resin. The foam core may comprise a high density, closed cell polyurethane foam that is formed of a desired size and shape. The fibers in the intermediate layer and outer layer may be, for example, chopped fibers, continuous longitudinally aligned fibers, circumferentially wound fibers, obliquely aligned fibers, or the fibers may have a woven or braided pattern. Multiple mandrel may be joined together to form complex mandrel shapes such as curves, ovals, and circles.

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.

An apparatus to prepare a preform for fabrication includes a mandrel, anchoring groove, anchoring device, tensioning groove, and tensioning device. The mandrel receives the preform. The mandrel has a first mandrel end and a second mandrel end. The preform has a first preform end and a second preform end. The anchoring groove is disposed at the first mandrel end. The anchoring device is configured and located to urge the first preform end towards the anchoring groove to secure the first preform end therebetween. The tensioning groove is disposed between the first mandrel end and the second mandrel end. The tensioning device is configured and located to urge a portion of the preform into the tensioning groove.

A method for preparing a machined surface of a composite article for diffusion bonding is provided. The method includes removing most of the exposed fibers by shot peening followed by acid etching. The acid etch may be followed by grit blasting and then another acid etch. After the method is applied to the surface, the article can be diffusion bonded to other composite article to form complex shapes.
