PROBLEM TO BE SOLVED: To provide a vehicle panel structure that achieves both ensured rigidity and vibration attenuation performance.SOLUTION: A vehicle panel structure with a panel member that is formed in a rectangular shape using synthetic resin as a base material and whose peripheral edge part is fixed to a panel support part of a vehicle body, comprises: a fiber dense part in which a plurality of reinforced fibers are arranged in the base material in a diagonal area of predetermined width, including a pair of diagonal lines of the panel member, so as to be straight continuous parallel to the diagonal lines and over the entire length of the diagonal area; and a fiber coarse part in which a plurality of reinforced fibers are arranged in an area other than at least the fiber dense part of the panel member so as to be straight continuous toward a plurality of directions and all the way from one end part to the other end part of the panel member. The fiber arrangement density of the fiber dense part is set higher than the fiber arrangement density of the fiber coarse part. The rigidity ratio of the Young modulus of the fiber dense part to the Young modulus of the fiber coarse part is set to equal to or greater than 7.4.SELECTED DRAWING: Figure 1
【課題】剛性確保と振動の減衰性能を両立可能な車両用パネル構造を提供すること。【解決手段】合成樹脂を母材として矩形状に形成され且つ周縁部が車体のパネル支持部に固定されるパネル部材を有する車両用パネル構造において、前記パネル部材の1対の対角線を含む所定幅の対角線領域に対角線と平行に且つ対角線領域の全長に亙って直線的に連続するように母材内に複数の強化繊維を配置してなる繊維密部と、前記パネル部材の少なくとも前記繊維密部以外の領域に複数方向に向けて且つパネル部材の端部から端部に亙って直線的に連続するように母材内に複数の強化繊維を配置してなる繊維粗部とを備え、前記繊維密部の繊維配置密度が繊維粗部の繊維配置密度より大きく設定され、前記繊維密部のヤング率と前記繊維粗部のヤング率の比の値である剛性比が7.4以上に設定されている。【選択図】図1
