Process and system of debundling fiber tow for use in preform mats and molding compositions containing such fibers
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.
Blended fiber mat formation for structural applications
A process and system are provided for introducing a blend of chopped and dispersed fibers on an automated production line amenable for inclusion in molding compositions as a blended fiber mat for structural applications. The blend of fibers are simultaneously supplied to an automated cutting machine illustratively including a rotary blade chopper disposed above a vortex supporting chamber. The blend of chopped fibers and binder form a chopped mat. The chopped mat has a veil mat placed on either side, and is consolidated with the veil mat using heated rollers maintained at the softening temperature of thermoplastic binder, with consolidated mats being amenable to being stored in rolls or as flat sheets. A charge pattern is made using the consolidated mat, and the charge pattern can be compression molded in a mold maintained at a temperature lower than the melting point of the thermoplastic fibers.
KNEADING METHOD FOR FIBER-REINFORCED THERMOPLASTIC RESIN, PLASTICIZING DEVICE, AND EXTRUDING MACHINE
The present invention provides a kneading method for a fiber-reinforced thermoplastic resin with which dispersibility of reinforcement fibers is enhanced and sufficient reinforcement fibers having a proper fiber length remain, and a fiber-reinforced thermoplastic resin plasticizing device and an extruding machine for carrying out the method. The kneading method comprises supplying a thermoplastic resin and reinforcement fibers into a cylinder of a plasticizing device, and rotating a screw to obtain a fiber-reinforced thermoplastic resin, wherein the size of a clearance between the bore of the cylinder and the screw is made different between an upstream side in the vicinity of a reinforcement fiber loading port and a downstream side, so that the clearance becomes larger from the vicinity of the reinforcement fiber loading port toward the downstream side compared with the upstream side.
Injection molding method and injection molding machine
Provided is an injection molding method for resin that contains reinforcing fiber, the method being capable of easily eliminating uneven distribution of added components. The injection molding method is provided with: a plasticizing step for supplying resin pellets P and added components to a cylinder equipped with a screw 10, which has a rotating axis as the center is capable of rotating normally and in reverse, and generating molten resin by rotating the screw 10 in the normal direction; and an injecting step for injecting the molten resin M comprising the added components into a cavity. In the plasticizing step, a reverse rotation operation for reversing the rotation of the screw 10 is performed or a screw-stopping operation of stopping the normal rotation of the screw 10 is performed with a prescribed timing and for a prescribed period.
