提出了用于机动车辆的纤维增强聚合物(FRP)复合材料部件、用于制造和使用这种部件的方法、以及具有整体FRP复合材料车辆车顶纵梁与面板结构的机动车辆。一种用于机动车辆的车辆车身结构包括一个或多个长形支撑纵梁,所述长形支撑纵梁中的每一个包括至少两个波状纵梁面板,这些波状纵梁面板连接在一起以在其间限定内部纵梁空腔。这些波状纵梁面板中的至少一个用FRP材料形成。车辆车身结构还包括用相同的FRP材料形成的主体面板。主体面板包括具有一个或多个阶梯式接口的主面板区段,每个阶梯式接口从主面板区段的相应侧横向地突出并在其上安装波状纵梁面板中的一个。主体面板和每个支撑纵梁的波状纵梁面板一体地形成为单件式、整体结构。

    Presented are fiber-reinforced polymer (FRP) composite components for motor vehicles, methods for making and using such components, and motor vehicles with unitary FRP-composite vehicle roof rail-and-panel structures. A vehicle body structure for a motor vehicle includes one or more elongated support rails, each of which includes at least two contoured rail panels that are joined together to define therebetween an internal rail cavity. At least one of these contoured rail panels is formed with an FRP material. The vehicle body structure also includes a body panel that is formed with the same FRP material. The body panel includes a main panel section with one or more stepped interfaces that each projects transversely from a respective side of the main panel section and mounts thereon one of the contoured rail panels. The body panel and a contoured rail panel of each support rail are integrally formed as a single-piece, unitary structure.
