Body Panels

A recent PM reminds me to submit this: http://www.kraussmaffei.co.uk/cref/dn.html. Dated but interesting.

There was some earlier up-to-date info here on an improved panel process.

Here 'tis (from MicroNut): http://www.prw.com/homePBP_NADetail_...de=1&curpage=0

More Body Panel Stuff

For the technical junkies, here's yet another article about the PP body panels. A few additional factoids are included. I like the idea of the inherant UV resistance:

Re: UV (A Short Diversion)

A bit ago this morning I emailed smartUSA a request that PAG ask smart GmbH to consider a factory option of UV-coated glass and panaramic roof to keep the cloth interior from fading. Nothing back yet, but we'll see.

Back to Body Panels

Are the three basic colors (black, white, yellow) molded-in-color (MIC) and the three metallics (red, blue, silver) painted?

smartUSA says that ALL body panels are painted and clear-coated. A follow-up inquiry to the UK (who have them in hand) got the same info (one response so far):

"That was always the case for the original smarts but based on methods introduced for the roadster and forfour, I believe all panels are painted for the new smart"

There may be more info later in the day.

Reading the technical articles extolling the smart car's new panels leaves me to believe they are impregnated colors not applied. The only application is for a clear coat.

Dunno. There have been 28 views of the UK inquiry so far, and no one has refuted the only response. Maybe a second call to smartUSA will get a different rep with different (better?) info. It would seem to me to be difficult to metallicise (word?) a MIC panel.

Another feed from Oslo: "Your impression is correct, the base colours are MIC, the others are painted. Not so for the roadster where all colours are painted.
Bjorn"

I'll keep trying to get a consensus from those who actually are in a position to say (like looking behind a piece of their own 451).

"Again, you may have seen this winner before, perhaps in the pages of IMM. Exterior body panels for the MCC Smart Car (subsidiary of DaimlerChrysler) also won the SPE International Automotive Div.’s award for innovation. As the first molded-in-color body panels, and the first to be interchangeable, these parts represent a true breakthrough for automotive plastics.
Dynamit Nobel (France) molds the panels using PC/PBT resin (Xenoy from GE Plastics). According to GE Plastics, molded-in-color panels are especially attractive for automotive OEMs putting in new plants, because they can avoid the $300 million-plus investment for a new paint line. Weight savings and reduction in the number of tools required are also reasons why the Smart Car panels swept both U.S. and international awards."

Seen that too, but there are some things that date it: references to "Daimler-Chrysler" (but that is a recent change); "MCC smart" (Micro Compact Car, a very old reference); "Dynamit Nobel" (that has changed too); "PC/PBT" (it is now a whole new material).

Fear not; we'll get to the bottom of it.

Fish, here's the latest from June 2007.

"Smart Pioneers First Full PP Body PanelsSmart® fortwo has become the first commercialised car to have full body panels manufactured from polypropylene (PP).
Date published: 06.11.07
Smart® fortwo has become the first commercialised car to have full body panels manufactured from polypropylene (PP). Borouge and Borealis, leading providers of innovative, value creating plastics solutions, have developed Daplen™ ED230HP, a thermoplastic polyolefin (TPO) compound, for this pioneering development to meet the cost-effective production targets and aesthetic, safety and environmental requirements of the latest Smart fortwo vehicle.
New Daplen ED230HP replaces a polycarbonate polybutylene terephtalate blend (PC/PBT), which is traditionally specified for exterior body panels, tailgates and hoods. To ensure a smooth transition to the new material, Borealis, Borouge’s European co-owner, worked closely with Smart and its Tier One supplier Plastal to provide engineering and simulation support in addition to the development of the material.
Smart’s selection of Daplen ED230HP satisfies its request for a faster production process. The new solution is an in-mass coloured compound, meaning colours are blended into the compound to provide ready moulded aesthetic parts. As a result, post-assembly painting steps are reduced with only a painted clear coat layer needed. In addition, a smooth paint finish can be more easily achieved.
Vehicle owners benefit from the material’s long-term resistance to UV exposure and outstanding paint adhesion. This helps to ensure quality aesthetics over the long term. In addition, when car repair is required, owners benefit from lower painting costs.
As a lightweight material used in all body panels, Daplen ED230HP provides a significant reduction in overall vehicle weight with 15%. For the end-user, this reduces fuel consumption and carbon dioxide emissions adding to the environmental friendliness of the car. Furthermore, the material is fully recyclable in line with European legislation.
Daplen ED230HP raises the safety performance of the latest Smart fortwo series. Its superior low thermal expansion creates zero gap tolerance between parts. This, in combination with an excellent impact/stiffness ratio for the injection moulded panels, leads to improved driver safety.
“Smart’s pioneering approach to using PP for full body panels in its fortwo series is a major step forward for the automotive industry and its suppliers,” Hu Wei, Vice President at Borouge, comments. “Daplen ED230HP has helped Smart tighten up its production process while raising the environmental, aesthetic and safety performance of its vehicle. We played a fundamental role in this development and are looking forward to seeing this advanced solution take-off within the industry.”
