Abstract: A process for the manufacture of polycarbonate particles is disclosed herein. The process includes combining a first solution including a polycarbonate and a phosphorus-containing flame retardant or a flame retardant polycarbonate, and an organic solvent with a second solution including a surfactant and an aqueous solvent substantially immiscible with the organic solvent, under conditions of shear and temperature effective to provide an emulsion. At least a portion of the organic solvent is removed from the emulsion to provide an aqueous slurry having a plurality of particles, wherein the particles include the polycarbonate and the phosphorus-containing flame retardant or the flame retardant polycarbonate.

Abstract: The method for producing a unidirectional carbon fiber tape, the method comprising: passing a first portion of a strand of fiber through an oven to carbonize the first portion, thereby converting carbon fiber precursor fiber of the first portion to carbon fiber, wherein the first portion comprises carbon fiber precursor fiber; and impregnating the carbon fiber of the first portion with thermoplastic matrix material to form impregnated fiber, while a second portion of the strand of fiber that is upstream of the first portion is passing through the oven to convert carbon fiber precursor fiber of the second portion to additional carbon fiber.

Abstract: A method of manufacturing a polyimide prepreg, including: coating a substrate with an aqueous polymer dispersion comprising polyimide particles having a spherical morphology and a volume based D100 diameter less than 100 micrometers and a volume based D90 diameter less than 60 micrometers and a volume based D50 diameter less than 40 micrometers, to form a coated substrate; and heating the coated substrate to form a polyimide prepreg. The prepregs can be formed into laminates or 3-dimensional composite articles.
