摘要： A system for debundling fiber tow into chopped fibers is provided that has one or more reels of fiber tow, a cutting element configured to receive the fiber tow to form chopped fiber, and a tube with introduced gas flow configured to receive the chopped fiber. A moving belt is positioned under the tube to collect the chopped fiber. A dispenser is positioned along the moving belt for applying a binder or additive. A treatment chamber receives the treated chopped fiber. A process for debundling fiber tow into chopped fibers is provided that supplies one or more reels of fiber tow to a cutting system, drops the chopped fiber into a tube with introduced gas flow to debundle the chopped fiber with a vortex, collects the chopped fiber exiting the tube onto a moving belt, chemically treats the chopped fiber, and provides the chemically treated chopped to a treatment chamber.

摘要： Provided is a device for manufacturing a chopped fiber bundle that is provided with a cutter roll obtained by attaching one or a plurality of disk blades on the outer circumferential surface of a roll core such that the rotation axis of the roll core matches the center axis, and a nip roll disposed in parallel with the rotation axis of the roll core, and that feeds reinforcing fiber yarn between the nip roll and cutter roll and continuously cuts the same, wherein the device is characterized by being provided with at least a rotary drive mechanism for rotating the cutter roll, and also being provided with a reciprocating drive mechanism for reciprocating drive of the cutter roll in the direction of the rotation axis of the cutter roll, and/or a traverse guide for traversing the reinforcing fiber yarn in the direction of the rotation axis of the roll core. Our invention provides a device for manufacturing a chopped fiber bundle that can, by means of a simple device, continuously cut the reinforcing fiber yarn obliquely, and further, that is provided with a traverse guide that makes inclined cutting at a small angle possible, and provides a method for manufacturing a chopped fiber bundle.

摘要： A process for debundling a carbon fiber tow into dispersed chopped carbon fibers suitable for usage in molding composition formulations is provided. A carbon fiber tow is fed into a die having fluid flow openings, through which a fluid impinges upon the side of the tow to expand the tow cross sectional area. The expanded cross sectional area tow extends from the die into the path of a conventional fiber chopping apparatus to form chopped carbon fibers, or through contacting tines of a mechanical debundler. Through adjustment of the relative position of fluid flow openings relative to a die bore through which fiber tow passes, the nature of the fluid impinging on the tow, the shape of the bore, in combinations thereof, an improved chopped carbon fiber dispersion is achieved. The chopped carbon fiber obtained is then available to be dispersed in molding composition formulations prior to formulation cure.

摘要： A blade cartridge for a fiber roving chopper comprises an annular support and a plurality of blade holders. Each of the plurality of blade holders comprises a main body portion, a first end, a second end, and a blade. The first end of the main body portion is connected to the annular support. The second end of the main body portion is opposite the first end such that the main body portion is cantilevered from the annular support. The blade is integrally seated in the main body portion and extends between the first end and the second end. In a further embodiment of the invention, the main body portion of the blade holder includes first and second end notches that extend through the main body portion and the blade.

摘要： A device for chopping fiber strand includes a form, and a strand feeding mechanism that delivers the strand to the form and conveys the strand along the form. First and second grinding wheels may be included to cut the strand into individual segments of desired length as the strand is conveyed along the form. A method of chopping a fiber strand includes the steps of delivering a continuous strand onto a base end of a form, conveying the continuous strand along the form from the base end toward a discharge end and cutting the continuous strand into individual segments of desired length, for example using first and second grinding wheels.
