Zusammenfassung: | To provide a center pillar for a vehicle in which while carbon-fiber-reinforced plastic and glass-fiber-reinforced plastic are alternately laminated to achieve reduction of weight of the center pillar, excellent rigidity of the center pillar can be maintained considering ceiling strength and side collision.SOLUTION: A center pillar according to the invention includes: a base layer which is formed of carbon-fiber-reinforced plastic; and laminated layers in which a large number of carbon-fiber-reinforced plastic and a large number of glass-fiber-reinforced plastic are alternately disposed on one surface and another surface of the base layer, respectively, and which is laminated and formed so that the carbon-fiber-reinforced plastic and the glass-fiber-reinforced plastic laminated on the one surface and the other surface of the base layer become symmetrical to each other with respect to a thickness direction of the center pillar.SELECTED DRAWING: Figure 5
【課題】炭素繊維強化プラスチックとガラス繊維強化プラスチックとを交互に積層して軽量化を達成しながら、天井強度及び側面衝突を考慮した優秀な剛性を維持することができる車両用センターピラーを提供する。【解決手段】本発明に係る車両用センターピラーは、炭素繊維強化プラスチックで形成されるベースレイヤーと、前記ベースレイヤーの一面及び他面にそれぞれ多数の炭素繊維強化プラスチックとガラス繊維強化プラスチックとが交互に配置され、センターピラーの厚さ方向を基準として前記ベースレイヤーの一面及び他面に積層される炭素繊維強化プラスチックとガラス繊維強化プラスチックとが互いに対称となるように積層されて形成される積層レイヤーと、を含むことを特徴とする。【選択図】図5 |
