劣るため、自動車用外板の様に優れた平滑性を要求され
る板体として用いるには不満がある。I'm trying to do it like this! To reduce the weight of the outer panel for iJJ cars,
It is advantageous to use materials with low specific gravity and high modulus of elasticity, but glass fiber reinforced resin plates are inferior in smoothness to steel plates, so they cannot have the same smoothness as automobile exterior panels. It is unsatisfactory to use it as a required board.

板体を提供することによって達成される。This purpose is such that at least the outer surface layer is formed of a sheet resin molding material using carbon fiber as a reinforcing fiber, and at least some of the other layers except the outer surface layer are filled with hollow glass particles. This is achieved by providing a laminate made of a sheet-like resin molding material.

6-2.84, flexural modulus 0.7-0.9X104 and 'Jf/1ry2, it can be seen that it is effective to use carbon fiber to obtain a lighter fiber-reinforced resin. . Moreover, the carbon fiber reinforced resin has a surface smoothness comparable to that of a steel plate, and can be used more advantageously than the glass fiber reinforced resin as a plate body where surface smoothness is important.

に使用され得る。Furthermore, if hollow glass particles with a small specific gravity are used as a filler, it is possible to further reduce the specific gravity of the fiber reinforced resin. Therefore, carbon 11 with excellent smoothness is added to the surface of the low specific gravity fiber reinforced resin layer filled with hollow glass particles.
A plate having an FA layer of fiber-reinforced resin can be effectively used as a plate requiring surface smoothness, such as an outer panel for an automobile, in place of a steel plate.
