The present invention relates to a vehicle body column structure using a fiber-reinforced resin composite material, which suppresses the breakage of a column using the fiber-reinforced resin composite material and enables the column to plastically deform to absorb collision energy when a side collision occurs. A vehicle body pillar structure using a fiber-reinforced resin composite material comprises: at least two tubular portions made of a fiber-reinforced resin, each tubular portion having an axis in the height direction of a vehicle body; and a metal plate that is disposed between any two cylindrical sections arranged in the front-rear direction of the vehicle body and that extends in the height direction of the vehicle body and in the width direction of the vehicle body.

    本发明涉及使用纤维增强树脂复合材料的车身柱结构,当发生侧面碰撞时,抑制使用纤维增强树脂复合材料的柱的断裂,使柱发生塑性变形来吸收碰撞能量。使用纤维增强树脂复合材料的车身柱结构包括:至少两个纤维增强树脂制的筒状部,其具有沿车身高度方向的轴;以及金属板,其配置在沿车身前后方向排列的任意两个筒状部之间,沿车身高度方向及车宽方向延伸。
