Abstract
A vehicle component is provided that includes a first cured layer of a molding composition having a predominant fiber filler chopped glass fibers, a second cured layer of molding composition having a predominant fiber filler chopped carbon fibers, and an elastomeric bonding agent with elongation properties configured to accommodate the differential coefficients of linear thermal expansion between the first cured layer and the second cured layer. The second cured layer is substantially devoid of glass fiber. The bonding agent is an elastomeric adhesive, which is operative from −40 to 205° C. The first cured layer forms an outer skin layer surface of a vehicle and the second cured layer forms an interior layer, where the outer skin layer surface has a class-A finish.
