Abstract:
Presented are multilayer composite panels for motor vehicles, methods for making/using such panels, and motor vehicles with transparent composite roof panels having localized reinforcement features. A sandwich-type multilayer composite panel contains one or more exterior layers each including a transparent rigid material, one or more bonding 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 attached directly to a bonding layer and/or exterior 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 localized to a discrete region within the composite panel's plan-view profile. This region has laterally spaced side rails extending along the length of the multilayer body panel, and one or more transverse crossmembers connecting the side rails.
