METHOD FOR MANUFACTURING A COMPOSITE TURBOMACHINE BLADED DISK (BLISK) WITH CERAMIC REINFORCEMENT
A method for manufacturing a metal bladed wheel of a turbomachine reinforced by an insert made of metal matrix composite material, includes winding the ceramic fibers around a mandrel in order to form the insert, the ceramic fibers being surrounded by a material constituting the matrix; and spark plasma sintering the insert with a powder of metal constituting the bladed wheel to be manufactured.
CONSOLIDATED COMPOSITES FROM METAL MATRIX COMPOSITE TAPE
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.
Multi-piece mandrel for CMC components
A mandrel for a molding process. The mandrel includes a first portion that has a first draft surface and a second draft surface. A second portion and a third portion are included. The second portion has a third draft surface and the third portion has a fourth draft surface wherein the first draft surface engages the third draft surface and the second draft surface engages the fourth draft surface. A channel extends along a length of the mandrel at an interface between the first, second, and third portions such that the second portion does not contact the third portion.

WIRE ADAPTED TO ELASTIC MEMBERS AND ELASTIC MEMBER
A wire adapted to an elastic member includes: a core that is made of metal or alloy and is elastically deformable; and an FRP layer configured to cover an outer surface of the core, and including fibers wound around the core, and thermosetting resin provided at least partially to the fibers and fixing the fibers to each other. A winding direction in which the fibers are wound around the core is along a direction of a tensile load out of the tensile load and a compressive load applied to the wire adapted to an elastic member based on a load applied from outside.
Systems and methods for manufacturing prepreg tapes
Systems and methods for manufacturing unidirectional fiber prepreg tapes for CMC articles are provided. In one exemplary aspect, the method includes casting a matrix material on a carrier film to form a matrix film. The matrix material of the matrix film is then allowed to dry for a predetermined time. The matrix film is then wrapped on a drum and the matrix material is wet to a predetermined viscosity with a solvent. Thereafter, a fiber tow that includes of a plurality of fibers is wound about the drum so that the fiber tow penetrates into the matrix material and the matrix material impregnates the fiber tow to form the prepreg tape.
