Corvette gets first carbon-fiber hood. (Composites).
The panels are produced by MacLean Quality Composites in West Jordan, Utah, an operating unit of MacLean Vehicle Systems, Mundelein, Ill. Weighing only 20.5 lb, the carbon-fiber hood is 10.6 lb lighter than the standard fiberglass SMC hood. The Class-A outer skin is only 1.2 mm (0.048 in.) thick, similar to stamped sheet metal, and is the thinnest plastic-composite skin on a production vehicle. (SMC typically is 2 to 2.5 mm thick.)
That outer skin is of carbon-fiber/epoxy unidirectional prepreg supplied by Toray Composites (America), Inc., Tacoma, Wash. The hood's inner structure is a hybrid of carbon-fiber SMC and low-density fiberglass SMC.
