摘要： 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.

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： A vehicle component includes a body, a first beam, and a second beam. The body has a first fixture region and a second fixture region. The first beam is formed of a first composite material and has a first beam shape. The first beam is attached to the body and extends between the first fixture region and the second fixture region of the body. The second beam is formed of a second composite material and has a second beam shape that is simple compared to the first beam shape. The second beam is attached to the body and extends between the first fixture region and the second fixture region of the body.

摘要： 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.

摘要： 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.
