The invention relates to reinforced composite inner roof panels of the sandwich-type having a cellular core. In a method for making a inner roof panel of the invention, a stack is formed that is made up of: an upper skin made of a reinforced thermoplastic material; a cellular core made of a thermoplastic material; and a bottom skin made of a reinforced thermoplastic material. The upper and lower skins and the cellular core are formed together and have regions of reduced thickness and regions of increased thickness that may provide head impact absorbing characteristics or form structural components of the passenger compartment. Examples of structural components that may be formed include HVAC ducts, wiring conduits, video display panel mounts or air bag receptacles.
