Abstract
A winding method and apparatus for producing a consolidated metal matrix composite is described. The methods are directed to winding softened metal matrix composite tape and layering the resulting softened metal matrix composite tape onto a rotating mandrel in a prescribed pattern on the surface of the mandrel to form a consolidated metal matrix composite. Upon cooling, the matrix metal solidifies and the resulting consolidated metal matrix composite may be removed from the mandrel. The consolidated metal matrix composites may be produced in a variety of shapes, such as cylinder, a tapered cylinder, a sphere, an ovoid, a cube, a rectangular solid, a polygonal solid, and panels.
Claims7
A method for forming a consolidated metal matrix composite, comprising the steps of:
- supplying metal matrix composite tape from a tape source to a rotating payout unit submerged in a metal bath, wherein the tape source and rotating payout unit are connected to a carriage;
- applying metal matrix composite tape from the rotating payout unit onto a rotating mandrel submerged in the metal bath;
- and
- moving the carriage laterally and substantially parallel to the axis of rotation of the rotating mandrel a predetermined distance and speed to provide overlapping layers of metal matrix composite tape around the rotating mandrel, whereby the tape source and rotating payout unit maintain a constant orientation as the carriage moves, and whereby the overlapping layers of metal matrix composite tape intermix and consolidate with adjacent layers of metal matrix composite tape to provide a consolidated metal matrix composite.
A metal matrix composite tape winding apparatus comprising:
- a furnace adapted to form and contain a metal bath;
- a rotating mandrel positionable within the furnace such that the rotating mandrel would be submerged upon the formation of the metal bath;
- and
- a tape source and a rotating payout unit connected to a carriage, wherein the rotating payout unit is positioned within the furnace such that the rotating payout unit would be submerged upon the formation of the metal bath, wherein the carriage is moveable laterally and parallel to an axis of rotation of the rotating mandrel, and wherein the carriage maintains a constant orientation of the tape source and rotating payout unit while the carriage is moving.
