摘要

The assembly (10) has a quarter panel (16) including a wall (18) having a preset total stiffness consisting of a combination of an outer panel (22) made of sheet steel having a preset stiffness, and an interior reinforcement skin (20) having another preset stiffness that doubles the outer panel, where the skin is made of carbon fibers. The skin doubles the outer panel only in a zone of the wall vulnerable to depression. The thickness of the outer panel is approximately 0.5 mm. The thickness of the skin is approximately 0.7 mm.
