<p>PROBLEM TO BE SOLVED: To provide an automobile panel having sufficient rigidity and good appearance, smooth, and retaining the shape thereof against heat.SOLUTION: An automobile panel has a hollow double wall structure composed of the outer side and inner side molded bodies. The outer side molded body comprises an inorganic filler-containing thermoplastic resin composition. The inner side molded body comprises a fiber-reinforced thermoplastic resin composition containing the inorganic and organic filaments, the rigidity thereof is 5 GPa or more but 15 GPa or less, and the linear expansion coefficient thereof is 60 ppm or below. The linear expansion coefficient of the outer side molded body is 70 ppm or below and is higher than that of the inner side molded body, but the difference between both values is 20 ppm or less.</p> |
