Shear controlled alignment of short carbon fibers in copper matrix composite green samples produced by powder injection molding

The tensile properties of short fiber reinforced composites are enhanced if fiber alignment in the load direction is achieved. Powder injection molding provides partial alignment of fibers in molded parts and shows a skin-core effect. The objective of this study was to align fibers completely in flo...
