Abstract:
1. A sandwich-type reinforced composite inner roof panel comprising: an upper skin made of a reinforced thermoplastic material; a cellular core bonded to the upper skin and made of a thermoplastic material and having an open-celled structure of the tubular or honeycomb cell type; and a bottom skin bonded to the cellular core and made of a reinforced thermoplastic material, the upper skin, the cellular core, and the bottom skin being formed to define an inner roof panel having varied thickness with reduced thickness areas in the majority of the inner roof panel and increased thickness areas in localized areas, the increased thickness areas being more readily compressed than the reduced thickness areas to provide integrally formed head impact absorbing members in the inner roof panel, wherein the core is crushed or partially deformed at the reduced thickness areas in the majority of the inner roof panel.
