Abstract: 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.

Abstract: 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.

Abstract: A process for resin transfer molding (RTM) with injection and overflowing of a resin through one or more troughs is provided that includes the injection of resin into a plurality of injection ports feeding the one or more troughs and overflowing the resin in into a mold. The temperature and pressure are controlled as applied to the mold. The injection ports are activated for injecting the resin in any order of individually, in groups, or pairings. A resin transfer molding (RTM) system for performing the process includes a mold having a cavity. A set of injection ports feed one or more continuous channels between the cavity and a reservoir of resin. A numerical controller selectively activates the injection ports to overflow the resin into the cavity in any order of individually, in groups, or pairing.

Abstract: A lightweight and simplified vehicle door assembly is provided with four main components, an upper frame positioned about the window, an inner frame structure, an outer body panel, and a composite reinforcement component. The composite reinforcement component provides an all-in-one solution for a side impact cross beam, as well as an upper door reinforcement, a front door pillar reinforcement, and a rear door pillar reinforcement. The composite reinforcement component acts to reinforce the overall door structure, offers resistance to a side impact that limits the intrusion into the passenger compartment, and offers resistance to a frontal impact by maintaining the spacing between the vehicle A and B pillars (for a front door) and pillar C and D for a back door. A coupe vehicle door in which there is no window frame may be reinforced with the composite reinforcement component. The composite reinforcement component may have continuous or chopped fibers.

Abstract: A process is provided for thermal molding an article with at least one layer of thermoplastic fibers that are non-woven and uni-directionally oriented in combination with at least one layer of reinforcing fibers. The reinforcing fibers including glass, carbon, nature based, and combinations thereof; alone or mixed with chopped thermoplastic fibers. Upon subjecting the layers to sufficient heat to thermally bond in the presence of non-oriented filler fibers, thermoplastic fiber fusion encapsulates the filler fibers. The filler fibers impart physical properties to the resulting article and the residual unidirectional orientation of the thermoplastic melt imparts physical properties in the fiber direction to the article. By combining layers with varying orientations of uni-directional fibers relative to one another, the physical properties of the resulting article may be controlled and extended relative to conventional thermoplastic moldings. The uni-directional fibers may have discontinuities along the length of individual fibers.

Abstract: An underbody assembly for a vehicle includes a plurality of polymer-fiber composite components. The polymer-fiber composite components include a base and a first reinforcement. The base includes a first side and a second side. The base is configured to extend in a longitudinal direction between a front of the vehicle and a rear of the vehicle. The first reinforcement is coupled to the base. The first reinforcement includes a first elongated ridge and a first elongated trough. The first elongated trough is disposed adjacent to the first elongated ridge. The first elongated ridge and the first elongated trough each extend transversely between the first side of the base and the second side of the base. In various aspects, the underbody assembly consists essentially of the polymer-fiber composite components.

Abstract: A process is provided for molding a resin matrix around a distribution of well distributed epoxy coated glass fibers to produce an article. The article is mass produced by the molding process based on a one or more layer structure, with an outer panel having a high degree of surface smoothness common to automotive body panels and a comparatively high tensile strength joinder thereto. The epoxy coated glass fibers are present in a single panel of an article or all such panels of a multiple layer article. The epoxy coated glass fibers can be present in an articles in a form of: chopped glass fibers that are intermixed and vary in orientation, a woven roving containing predominately epoxy glass fibers with carbon fibers dispersed there through, or non-woven fiber mats.
