Abstract: A method of making a laminate component and method of removing voids from a pre-preg ply and pre-preg component are provided. The method of making a laminate includes laying up a plurality of pre-preg plies in a desired geometry, the plurality of pre-preg plies having a plurality of fibers and a resin. The method includes creating at least one void-reducing channel in at least one ply of the plurality of pre-preg plies, the void-reducing channel being perpendicular to a fiber orientation in the at least one ply. The void reducing channel locally re-orients the fibers adjacent to the void-reducing channel in the at least one pre-preg ply. The method includes laminating the plurality of pre-preg plies. The resin fills the at least one void-reducing channel and the laminate component has a porosity margin of about 1.5%.

Abstract: A method of separating a powder mixture is disclosed. A first magnetic field is applied to the powder mixture which may contains a non-magnetic metal powder and a contaminant powder. A field strength of the first magnetic field magnetizes the non-magnetic metal powder and leaves the contaminant powder non-magnetized. A second magnetic field is applied to the powder mixture to separate the magnetized metal powder from the non-magnetized contaminant powder.
