Abstract
Description
なお、第1工程における接着剤層の積層は電着塗装としてもよい。また、第1工程では、接着剤層18を配置する前に本体部13を脱脂処理してもよい。若しくは、接着剤層18の車両前後方向後側面全体を粗面化処理(例えば、プラズマ処理など)してもよい。上記処理などを行うことで、本体部13と接着剤層18との接合面積が増加し、接合強度を高めることができる。
次に、本実施形態の作用並びに効果について説明する。
上記実施形態では、補強部材16が接着剤層18に埋設されているため、補強部材16の面方向外側端部16Aが接着剤層18に覆われている構成としたが、本発明はこれに限らない。図8(A)に示されるように、補強部材16が、接着剤層18に埋設されない構成としてもよい。つまり、補強部材16と接着剤層18が面方向に沿った接合面U1のみで接合される構成としてもよい。
又は、図8(C)に示されるように、補強部材16が接着剤層60に埋設されない構成とし、接着剤層60の端部層60Bの断面形状を、車両前後方向に沿った断面視で三角形状としてもよい。
若しくは、図8(E)に示されるように、補強部材16が接着剤層70に埋設されない構成とし、接着剤層70の端部層70Bの外側表面を、車両前後方向前後側(本体部13側)に凸をなす円弧状に形成してもよい。
次に、図9及び図10を用いて、第2実施形態に係る車両構成部材としてのドアインパクトビーム80ついて説明する。なお、前述した第1実施形態と同一構成部分については、同一符号を付してその説明を省略する。この第2実施形態に係るドアインパクトビーム80は、アルミニウム合金等の金属製の本体部82に接着剤層18を介して補強部材16が接合されている。
本実施形態においても、前述した第1実施形態の構成を基本的には踏襲しているので、同様の作用・効果が得られる。
次に、図11及び図12を用いて、第3実施形態に係る車両構成部材としてのBピラー90ついて説明する。なお、前述した第1実施形態と同一構成部分については、同一符号を付してその説明を省略する。この第3実施形態に係るBピラー90は、アルミニウム合金等の金属製の本体部92に接着剤層18を介して補強部材16が接合されている。
