To provide a vehicle body skeleton component which can improve collision energy absorbed by bending when a collision load is inputted from a side of a vehicle body and a production method of the vehicle body skeleton component.SOLUTION: A vehicle body skeleton component 1 has: a member with a hat-shaped cross section or a member with a U-shaped cross section that has a top plate part 3a, and a pair of vertical wall parts 3c which is continuous from the top plate part 3a via a punch shoulder R part 3b; a resin layer 7 formed on an external surface of at least the punch shoulder R part 3b of the member with a hat-shaped cross section or the member with a U-shaped cross section; and a thin wall patch member 11 which is so provided as to straddle the top plate part 3a and covers a surface of the resin layer 7 from an external surface side, and of which both ends are joined to external surfaces of the pair of vertical wall parts 3c. The coated or pasted resin layer 7 is bonded an external surface of the member with a hat-shaped cross section or the member with a U-shaped cross section and the thin wall patch member 11 at bond strength of 10 MPa or more at a room temperature after being heated, and tensile strength of the thin wall patch member 11 is lower than that of the member with a hat-shaped cross section or the member with a U-shaped cross section.SELECTED DRAWING: Figure 1
【課題】車体の側方から衝突荷重が入力した際に、折れ曲がることで吸収する衝突エネルギーを向上することができる車体骨格部品及び該車体骨格部品の製造方法を提供する。【解決手段】本発明に係る車体骨格部品1は、天板部3aと、天板部3aからパンチ肩R部3bを介して連続する一対の縦壁部3cとを有する断面ハット形部材又は断面コ字状部材と、該断面ハット形部材又は断面コ字状部材の少なくともパンチ肩R部3bの外面に形成された樹脂層7と、天板部3aを跨ぐように配設されて樹脂層7の表面を外面側から覆うとともに、両端部が一対の縦壁部3cの外面に接合された薄肉パッチ部材11と、を有し、塗布又は貼付された樹脂層7は、加熱された後に室温で10MPa以上の接着強度で前記断面ハット形部材又は断面コ字状部材の外面及び薄肉パッチ部材11に接着されており、薄肉パッチ部材11の引張強度は、前記断面ハット形部材又は断面コ字状部材より低強度であることを特徴とする。【選択図】 図1
