Exterior panels for motor vehicles

摘要

An exterior panel (10) for a motor vehicle has a coefficient of linear thermal expansion of less than 20x10-6 inches of expansion per inch material per degree Fahrenheit. The exterior panel (10) comprises a rigid structure (14) formed from at least one thermoplastic material and reinforcement particles dispersed within the at least one thermoplastic. The reinforcement particles comprise less than 15% of a total volume of the rigid structure. At least 40% of the reinforcement particles have a thickness less than about 50 nanometers. A decorative coating layer (12) having at least one coloring agent is disposed on the rigid structure (14).
