Abstract
A sandwich panel for an automobile includes a core layer, a surface layer, and an adhesive layer. The core layer includes glass fibers and thermoplastic resins and defines an optimal weight and thickness to provide flexural performance and non-flammability. The sandwich panel provides a flame barrier layer, which is a non-combustible layer during ignition and prevents flame from leaking to the outside of the panel.
