Method and apparatus for winding a tape smoothly onto an irregularly shaped mandrel or the like, including ends, characterized by tape storage and unreeling of packaged reels of tape to be wound smoothly onto the mandrel, mandrel rotational motor and gearing supporting and rotating the mandrel; delivery head roller for winding the tape onto the mandrel, a creel carrying the tape reel assembly, a creel rotating means adapted to rotate the creel to desired positions, an in-feed means carrying the creel and adapted to traverse normal to the mandrel, a traversing carriage carrying the in-feed means and adapted to traverse longitudinally of the mandrel; a controller for effecting movement of all the machines elements. The roller is freely rotatable and is pivotally mounted such that when moved longitudinally of the mandrel in both directions with the tape passing over it, the tape is wound smoothly onto the mandrel. The method of winding the tape smoothly onto the mandrel comprises employing the foregoing and unwinding the tape from the reel and supplying it untwisted to the freely pivotal head roller under the desired tension while following the envelope of the mandrel and while moving in both directions along the mandrel and rotating the mandrel such that the tape is wound smoothly onto the mandrel in a true helical pattern yielding complete coverage.

A method for manufacturing composite parts includes positioning a plurality of composite layers on an application surface formed by a plurality of tooling members and filler members on a mandrel. A part formation aid is disposed on the composite layers above each tooling member. The filler members are then removed, and the composite layers slit over the recesses. The mandrel, the tooling members, the composite layers, and the part formation aids are placed in a vacuum bag. As the bag is evacuated, each part formation aid forces the side edge of the composite layers formed by the slit around the respective tooling member, thereby forming a composite part with a desired shape, thickness, and density. In an alternate embodiment, a flanged composite panel is formed around a rectangular mandrel after positioning composite layers on an outer surface of the mandrel and an outer surface of a filler member disposed on one end of the mandrel. After removing the filler member, the flanged panel is formed and partially cured by vacuum bagging. A plurality of tooling members and filler members are then placed on the flanged panel to form an application surface. Composite layers are positioned on the application surface, and then the filler members are removed. Vacuum bagging is used to produce a plurality of stiffeners around the tooling members and directly adjacent to the flanged panel. The stiffeners and flanged panel are co-cured to produce a single and integral part.
