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 preform for thermoset resin composition molding is provided that upon cure forms a variety of molded and fiber reinforced articles used in a variety of applications such as vehicle components including bed lines, body components, trim, interior components, and undercar components; architectural components such as trim and doors, marine components including hulls, trim, and cockpit pieces; and similar structures in aerospace settings. A novel slurry composition, a novel centrifugal process, or a combination thereof provide superior quality preforms that are created with greater throughput relative to conventional techniques. The inhibition of fiber movement between the time such a fiber contacts the mold, or fibers already in place on the mold, and the time the fibers are set in position provides a superior fiber homogeneity and randomized orientation relative to existing slurry techniques with attributes of low scrap generation, and process flexibility with respect to part shape and fiber material.

Abstract: A polyurea additive is provided that strengthens a given base sheet molding composition (SMC) An isocyanate containing species and an amine containing species are introduced into an uncured polymeric resin of a sheet molding compound (SMC) under conditions suitable for the formation of a polyurea polymer network. Upon cure of the SMC base resin, an interpenetrating network is formed that is stronger than the base SMC absent the polyurea. As a result, an article is formed from the SMC that is stronger at the same dimensions than a conventional article or thinned to achieve the same properties to obtain a lightweight article compared to that formed from conventional SMC. The properties of the article are also attractive relative to aluminum for the formation of vehicle body and exterior panels.

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 is provided to reclaim carbon fiber from a cured vinyl ester, crosslinked unsaturated polyester, or epoxy thermoset matrix. The composite pieces are added to a polyol solvent composition under to conditions to free more than 95% by weight of the carbon fiber from the composite. The freed carbon fibers are washed and dried to reclaim carbon fiber reusable to reinforce a polymer to form a new FRC article. Solvents are chosen that are low cost and low toxicity. Processing is further facilitated by techniques such as solvent pre-swell of the particles, microwave heating, and sonication to promote thermoset matrix digestion to free reinforcing carbon fibers.

Abstract: A molding composition formulation is provided that includes polypropylene, glass fiber, and a cellulosic powder used as a filler. The filler may be at least one of coconut shell powder, walnut shell powder, or rice hull. The molding composition formulation may further include natural cellulosic fiber illustratively including at least one of coconut fibers, bamboo fibers, sugar cane fibers, or banana skin fibers. The molding composition may be compression moldable long fiber thermoplastic (LFTD). The molding composition formulation may be used in thermoforming. In a specific embodiment of the molding composition, the formulation proportion of the polypropylene is 50 to 60 percent of the formulation; and the polypropylene substitute is 5 to 15 percent of the formulation, and in an alternative embodiment, the formulation proportion of the polypropylene is 40 to 80 percent, the cellulosic powder is 1 to 25 percent, and the glass fiber is 1 to 50 percent.

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.
