ABSTRACT:
A surface-reinforced article includes a core assembly (12) comprising a foam core (20) with a surface region (22) that includes fine fibers, and an outer reinforcing covering (14) which includes thicker fibers in a resin (30). The fine fibers includes coupling fibers (100) with outer ends (106) embedded in the resin. After the core assembly is molded, the spacers are removed, the core assembly is wrapped in the outer fibrous material, and the wrapped core assembly (120) is placed in the second mold cavity that is formed by the original mold but without the spacers.
