The invention relates to a laminated composite roof panel with internal local structural reinforcement for a motor vehicle. Multi-layer composite panels for motor vehicles, methods for making/using such panels and motor vehicles with transparent composite roof panels having local reinforcement features are presented. A sandwich type multilayer composite panel includes one or more outer layers each including a transparent rigid material, one or more binding layers each including a transparent adhesive material, and one or more structural reinforcement layers each including a fiber reinforced polymer material. Each structural reinforcement layer may be directly attached to the bonding layer and/or the outer layer. The composite panel may also include one or more IR reflective layers, one or more light absorbing sunshade layers, and one or more insulating low-k layers. The fibers of each structural reinforcement layer are confined to discrete regions within a plan view profile of the composite panel. This region has laterally spaced edge beams extending along the length of the multi-story body panel, and one or more transverse cross members connecting the edge beams.
本发明涉及用于机动车辆的带内部局部结构增强件的层压复合车顶板。提出用于机动车辆的多层复合板、用于制成/使用此类板的方法以及带有具有局部增强特征的透明复合车顶板的机动车辆。夹层类型多层复合板包含均包括透明刚性材料的一个或多个外部层、均包括透明粘合材料的一个或多个结合层以及均包括纤维增强聚合物材料的一个或多个结构增强层。每一结构增强层可以直接附接到结合层和/或外部层。复合板还可以包括一个或多个IR反射层、一个或多个光吸收遮阳层以及一个或多个绝缘低k层。每一结构增强层的纤维被局限到复合板的平面图轮廓内的离散区域。此区域具有沿着多层车身板的长度延伸的侧向隔开的边梁,以及连接边梁的一个或多个横向横梁。
