In modern cars most of the interior components (e.g. dashboards) are based on a three-layer composite construction. This structure combines ideal strength properties with high freedom of design and good touch behavior. But it shows also significant disadvantages. Especially the relatively high weight of approx. 4.2 kg of current dashboards is a drawback. The reason for this high weight is the use of a PUR foam component with a density of approx. 100-150 kg/m³ in combination with a glass fiber reinforced PP inlay with a density of approx. 600 (foamed version) - 1200 kg/m³ (compact version). The problematic behavior of recycling due to the combination of Duromers (PUR spray skin, half rigid polyurethane foam) and Thermoplastics is a disadvantage of this conventional construction. The discribed new concepts for modern automotive interior parts are based on polypropylene (PP) and they have a core of expanded polypropylene particle foam (EPP) and a decorative layer of a thermoplastic polyolefin elastomer (TPO) film. Compared with conventional solutions in the automotive interior area they are characterized mainly due to the avoidance of material mixtures so that they have better recycling properties and in spite of comparable crash performance they are significantly lighter (approx. 25 %). Because of the well directed combination of the positive properties of the components (especially rigidity of the carrier, lower density combined with better crash behavior of the EPP foam core and good haptically and optical properties of the film) the multi-material system compensates the disadvantages of the individual components. And moreover the integration of all process steps to a new single step manufacturing process in combination with the waiver of an additional surface treatment the new ultralight concept should lead to a significant reduction in the costs (approx. 20 %) and the cycle time (approx. 35 %).
