Objectives 3 To apply the knowledge developed and collected within the project to an industrial demonstrator. The PEGASUS methodology can apply to any plastic car component but this demonstrator is based on a completely new rear part of a Smart* car. - Integrated t rear quarter panel and complete rear lamp assembly * Smart is a Daimler AG company
Demonstration Rear panel / fender design 4 Product Design Rear lamp Fender Fender with integrated rear lamp
Demonstrator Steps 5 Technology integration: Design Rear light assembly Moulding of rear panel Painting Assembly Testing Economic and environmental impact Incorporating: Intrinsic colouring nano-pigments, conductive pathways, overmoulding, de-bond on command adhesive
Product development: Design 6 Product design: To design the new component integrating i the different parts. The functional requirements were fed into the IDEE and the optimal materials and processing routes identified. IDEE supports mould design based on simulations such as MouldFlow, processing parameters, Life Cycle and cost analysis. Product manufacturing: To manufacture the newly designed component using the new materials developed within the project and the options obtained from IDEE analysis.
Design 7 Product development: Process performance evaluation: The Raw materials technical, economic and environmental aspects were determined and compared against a benchmark. End of life Production The new part was designed to replace an existing car component. This allowed comparison of the results with the existing part where all the information is already available.

8 Technology integration ti LEDs in Automotive Lighting
Technology integration LEDs in Automotive Lighting 9 LEDs used instead of conventional lights, this has become increasingly popular during the project for the following reasons: LEDs considered as alternative lighting due to space and cost savings Expected LED-life is comparable to part-life, no need for intermediate repair Significant reduction in energy consumption (compared to conventional lamps) Better for the environment, LEDs contain no mercury or heavy metals Pegasus new technology: Conductive path and Over Moulding Lines of injected conductive polymer, connect pins from the plug to the LEDs LEDs are overmoulded for increased integration
Technology integration Mould for LEDs overmoulding 10 Issues related to the integration of temperature and pressure sensitive LEDs in polymer processes required investigation. A simple mould (designed to be used in a micro injection machine) was designed to evaluate LEDs resistance to injection moulding temperatures and pressures. LEDs placed inside the p cavity
Experiments showed that: Technology integration LEDs withstand injection temperatures and pressures Tolerances in LEDs dimensions are acceptable. LED trials 11 A compound from EU Sixth Framework project PolyCond, contract number NMP2-CT-2005-515835, was the one that presented the best results with maximum output intensity of the LEDs.
Technology integration LEDs Layout 12 LED array had to: Fit existing part geometry Cover entire area Meet brightness regulations Number of LEDs needed Red/orange Amber Turn - 7 to 14 Stop 5 to 10 - Rear fog 10 to 20 -
13 Technology integration ti Conductive pathway
Technology integration - Conductive Path 14 Studies with LED overmoulding proves that it is possible to inject the entire conductive path with a conducting polymer. Metallic pins from the plug However, in this case the part geometry meant that the conductive pathway would be too narrow for a complete solution. A metallic insert will be used to connect the LEDs but the path from this insert to the metallic pins of the plug will be injection moulded using conductive polymer.
15 Technology integration ti Part design
Technology integration - Part Design 16 Bright blue areas are new developments to the housing for the integration into the fender. The PMMA lenses had to be trimmed to fit the new housing. Plug Lines of conductive path
Technology integration Part Design 17 Pegasus new technology: Debond-on-command After injection moulding of the housing part (with the LEDs and the conductive path), the debond - on - command glue is applied to the housing. It is then placed in contact with the lens, thus obtaining the Rear-Light part.

Due to time constraints the panels will be given the standard conventional clear coating currently used by SMART. Demonstration - Painting 31 Ideally, a powder coating under development in the project would have been used. Once fully developed these coatings will offer advantages such as eliminating solvents, less wastage and smaller paint shops.
