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.

METHOD FOR MANUFACTURING METAL MATRIX COMPOSITE PARTS

A method of manufacturing metal matrix composite (MMC) parts, including the steps of applying a metallic sheath around a bundle of MMC laminates, heating the bundle of MMC laminates in the metallic sheath at a curing or fusing temperature to consolidate the bundle of MMC laminates into a single cured or fused part, and then cooling the cured or fused part. The bundle of MMC laminates may be formed by removing surface contamination from the dry reinforcement fibers, creating a plurality of individual MMC laminates by plating dry reinforcement fibers with electroless nickel, and/or electrodeposited nickel or cobalt, and stacking each of the plurality of individual MMC laminates into a bundle. Autocatalytic and/or electroplating may be used as the primary means to incorporate fiber reinforcement into the metal matrix composite by covering and bonding fiber reinforcement into MMC laminates/plies and/or 3-D woven parts.

Apparatus and process for producing additive manufactured metal matrix composites and article of manufacture thereof

A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.
