<P>PROBLEM TO BE SOLVED: To economically provide a resin-made panel which is light in weight compared with a conventional resin panel and improved in rigidity. <P>SOLUTION: A vertical panel component for a vehicle is formed by compounding a resin molding, and when necessary, parts including a window with a reinforced structure comprising the molding of a fiber reinforced material containing reinforcing fiber having a specific elastic modulus of ≥50 GPa.cm<SP POS="POST">3</SP>/g, and simultaneously satisfies following (1) and (2). When the projection area of the whole structure in the projection at a projection angle at which the projected area of the structure becomes maximum is defined as S1 and the projected area of only the reinforced structure in the projection at the same projection angle is defined as S2, a relation of S1 and S2 is 0.60>S2/S1>0.05 (1). When the polar second moment about the figure center of a projection drawing of the whole structure in the projection at a projection angle at which the projected area of the structure becomes maximum is defined J1 and a polar second moment about the figure center of the whole structure of the projection drawing of only the reinforced structure in the projection at the same projection angle is defined as J2, a relation of J1 and the J2 is 0.95>J2/J1>0.20 (2). <P>COPYRIGHT: (C)2012,JPO&INPIT |
