摘要

Premium automobiles have sought to maximize performance through power trainrntechnology, aerodynamic and body advancements that reduce the overall weight ofrnthe vehicle. Carbon composite structures have long been demonstrated in fighter jets,rncommercial airliners and racecars to be the material of choice to save weight andrnincrease performance. Even with nearly unlimited budgets, these low volume vehiclesrnhave had to compromise cost for weight. Here the use of carbon composites has beenrnquite often limited to large flat parts from woven carbon fibers, fabric, andrnunidirectional tape. Carbon is supplied in "flat sheets" or as a cloth. This makes itrntime consuming to fabricate complex shapes with changes in thickness, ribs, bosses,rnand even threads.rnIncreasing the application of carbon composites beyond current components hasrnrequired unattractive cost compromises of tedious hand lay-up, large reductions inrnthe material properties or the return to a standard and often heavier metal part.rnHexMC, carbon epoxy molding compound, is the material that can bridge the cost ofrncomplex fabrication.rnThe paragraphs that follow will address the potential application of HexMC intornvehicle components while exploring the current use of carbon molding material inrnhigh performance personal equipment. Molding and application of HexMC requiresrnthe understanding of the product configuration and part processing. Design criteriarnbeyond just properties will complete the discussion.
