Embodiment 1

[0057] By providing a bundle of 6 strands (tow) of 10000 denier alumina fibers (obtained from 3M Company under the tradename 610), making it pass through a set of aperture guides and positioning rollers to prepare a wire wound metal matrix composite cylinder. The fiber bundle was introduced into a molten aluminum bath maintained at about 1350°F. Molten aluminum is produced by melting aluminum (99.99% Al). Molten aluminum is infiltrated into the fiber bundles by ultrasonic vibrations. Ultrasonic vibrations are provided by a waveguide connected to an ultrasonic processor. The waveguide included a 1 inch diameter Ti-6Al-4V (wt%) extender and a pure Nb tip. The Nb waveguide tip was set within 0.050" of the fiber bundle and operated at 20 kHz. The front end of the fiber bundle was connected to a mandrel, which was connected to the motor via a cross link and a manual screw drive mechanism, the cross The connecting rod is used to control the rotation, and the manual transmission...

Embodiment 2

[0059] A bundle of 6 strands (tow) of 10000 denier alumina fiber (obtained from 3M Company under the trade name Nextel 610) was provided by feeding it through the creel with a tensioned spool. A series of tensioned rolls, hole guides, and positioning rolls to produce a wire-wound metal matrix composite cylinder. The fiber bundle was introduced into a molten aluminum bath maintained at about 1350°F. Molten aluminum is produced by melting 99.99% aluminum. Molten aluminum is infiltrated into the fiber bundles by ultrasonic vibrations. Ultrasonic vibrations are provided by a waveguide connected to an ultrasonic processor. The waveguide included a 1 inch diameter Ti-6Al-4V (wt%) extender and a pure Nb tip. The Nb waveguide tip was set within 0.050" of the fiber bundle and operated at 20 kHz. The front end of the fiber bundle was connected to a mandrel attached to a filament winder (McClean-Anderson, Schofield, WI) through rotation of the mandrel The fiber bundle is drawn throug...

Abstract

A wet wire winding method and apparatus for preparing cured metal matrix composites is described. The method involves winding a softened metal-infiltrated fiber bundle and laminating the resulting softened metal-infiltrated fiber bundle on a rotating mandrel in a predetermined pattern on the surface of the mandrel to form a cured metal matrix composite. Upon cooling, the matrix metal solidifies and the resulting solidified metal matrix composite can be removed from the mandrel. Cured metal matrix composites can be formed into a variety of shapes such as cylindrical, tapered cylindrical, spherical, oval, cubic, rectangular solid, polygonal solid, and flat plate.

Description

technical field [0001] The present invention relates to cured metal matrix composites ("MMCs") and methods and apparatus for making these composites. More specifically, the present invention relates to the direct winding of softened metal infiltrated fiber bundles for the preparation of cured metal matrix composite parts. Background technique [0002] Next-generation high-tech materials for aerospace and aircraft applications need to have high temperature resistance, high stiffness and high strength. Components made from laminated metal matrix composites, unlike those made from monolithic materials, have the potential to meet these requirements, thereby significantly improving the designer's ability to meet the required high temperature, structural strength, and stiffness specifications while minimizing weight . [0003] These types of laminated metal matrix composites typically have long continuous lengths of reinforcing fiber material, such as alumina, in a metal matrix ...
