To reduce the weight of a frame supporting a relatively thin roof panel.SOLUTION: A vehicle roof stiffener 200 includes a metal or metal alloy frame 202 defining a central opening 204 and at least one corner. The vehicle roof stiffener also includes a fiber reinforced polymer (FRP) portion including at least one transition structure comprising a metal or a metal alloy. At least some of the fibers of the FRP portion are embedded in the transition structure. The FRP portion is located in the at least one corner. In some examples, the frame includes an opening in the at least one corner, and the FRP portion spans the opening. In other examples, the FRP portion overlaps the frame at the at least one corner. The FRP portion located at the corner may improve rigidity of the roof stiffener to increase resistance to a racking motion and increase the overall stiffness of the vehicle.SELECTED DRAWING: Figure 3A

    【課題】比較的薄いルーフパネルを支持するフレームの重量を低減する。【解決手段】乗物ルーフ補強材200は、中央開口部204及び少なくとも1つの角部を規定する金属又は金属合金フレーム202を含む。前記乗物ルーフ補強材は、さらに、金属又は金属合金を含む少なくとも1つの移行構造を含む繊維強化ポリマ(FRP)部を含む。前記FRP部の繊維の少なくともいくつかは、前記移行構造に埋め込まれる。FRP部は、前記少なくとも1つの角部に配置される。ある例において、前記フレームは、前記少なくとも1つの角部内に開口部を含み、前記FRP部が前記開口部に広がる。他の例において、前記FRP部は、前記少なくとも1つの角部で前記フレームに重なる。前記角部に配置される前記FRP部は、ルーフ補強材の剛性を改善し、ラッキング動作に対する耐性を増加させ、全体的に乗物の剛性を増加させてもよい。【選択図】図3A
