Abstract: A system is provided for producing composite products including a substrate and a resin integrated with the substrate.

Abstract: This disclosure includes dispersions for impregnating arrangements of fibers with thermoplastic materials and systems for and methods of using the same. Some dispersions include an aqueous solution and particles, each including a thermoplastic material, such as polycarbonate, dispersed within the solution, wherein ones of the particles having a diameter that is less than or equal to 50 micrometers (?m) account for at least 50% of the mass and/or the volume of the particles, and: (1) ones of the particles having a diameter that is greater than or equal to 55 ?m account for at least 5% of the mass and/or the volume of the particles; and/or (2) each of the particles includes one or more additives, such as a flame retardant, dispersed throughout the thermoplastic material.

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.
