摘要

One of the "holy grails" of carbon fiber application is car wheels. How ' badly would auto OEMs love to lose those heavy steel wheels? The question always has been: Can a carbon fiber wheel meet all of the required performance specs at an affordable price? The short answer is, yes but not yet. Dymag Racing UK (Ghippenham, U.K.) has developed a carbon fiber wheel that meets or exceeds many of the performance requirements of a car wheel, but price, for now, leaves this product in the high-performance category. The future, however, looks bright. Bevis Musk, Dymag's marketing director and technical director of composites development, says the wheels comprise a forged magnesium hub/spoke system that is fastened to a carbon fiber rim by specially coated titanium fasteners. The rim is molded from a Toray Carbon Fibers America Inc. (Flower Mound, Texas) dry weave carbon fabric supplied by Sigmatex High Technology Fabrics Inc. (Runcorn, U.K.) and infused with a high-performance epoxy from Huntsman (The Woodlands, Texas) in a proprietary RTM-like process that Musk calls "high-pressure casting." It uses a solid metal casting-type mold with injection at 50 psi to 75 psi (3.45 bar to 5.17 bar). A key to process success is a lacquer-based coating that, when applied to the mold surface, serves as the mold release, but at demolding adheres to the rim, providing a durable finish that resists ultraviolet light brake-dust, salt and other corrosives encountered by race and road cars. According to Musk, the wheels come out of the tool to spec and ready to use.
