The new research projects will be funded in three areas of materials R&D: predictive modeling of carbon fiber composites, predictive modeling of advanced steels, and developing advanced alloys for automotive and heavy-duty engines.
Projects selected in the first area will involve developing and validating modeling tools to optimize carbon fiber composite performance and cost-effectiveness for use in vehicle bodies, chassis, and interiors. Carbon fiber composites can reduce the weight of vehicle components by up to 50 percent over conventional automotive steel structures.
The second R&D area will concern developing modeling tools to help optimize performance and cost-effectiveness of third-generation high-strength steels to be used in vehicle bodies and chassis. The DOE stated that such advanced steels can reduce the weight of vehicle components by more than 25 percent.
The third area of research has a different goal: to develop low-cost, high-strength alloys for manufacturing engine blocks and cylinder heads used in automotive and heavy-duty trucks. Cast engine components must be strong enough to withstand higher cylinder pressures caused by more efficient engines that also run hotter.
As much as $8.2 million of the funding will be made available in fiscal 2012. An additional $6 million will be available the following year, assuming Congress gives its approval. The projects are expected to take between two and four years to be completed. The Energy Department is accepting applications from a variety of sources, including national laboratories, university led-teams, and industry.
Well, if there isn't yet a database compiling all of that data, there needs to be, hence why it makes sense that predictive modeling and simulation eat up a sizeable chunk of the funding. Given how easy it is to slant performance metrics and position claims, there needs to be some trusted record of data to draw on so engineers in these fields, using these new materials, can make the best, most informed design choices.
The one thing I already worry about with small city cars is, what about all those huge trucks and buses they could run into? The safety standards would have to protect against low-speed crashes with huge vehicles, as well as with other small cars.
Beth, I also noticed the emphasis on predictive modeling. The announcement (link given in the article) is quite brief and doesn't give any more details. Having covered this subject before a little, I suspect it might be aimed at discovering which materials perform best, according to certain specs, for which specific applications, meaning, in different components of the car. I would guess that those specs would combine the required material performance characteristics (toughness, strength, impact resistance, chemical resistance, etc.) of that component with weight saved. To date, AFAIK there's no such automotive materials database, at least for composites or for composites vs metals, only many different manufacturers' claims and specs and tests. If anyone knows any different, please chime in.
This doesn't seem like much money for R&D, especially since it is spread out of a number of years. This may simply be the most the White House could put together without congressional approval. The load for the company in Dearborn woud have been massive. But in our current political climate, I can see why it didn't get through.
@TJ: That's an interesting idea. But, would it work in the US given that our car culture is centered on independence and mobility. Could another possibility be to beta test newer technologies in public transportation or partner with delivery companies, such as UPS or FedEx?
I haven't been following this issue closely. Why is it interesting that the DOE's announcement came the day after the American Iron and Steel Institute released its industry profile?
I think one way to help with this goal would be a new safety class, for light weight vehicles intended for city use, at lower speeds. The vehicle can be lighter, the safety equipment reduced. Lighter weight, lower cost, better fuel efficiency, all without the need for new materials (though such materials would also help with this class).
Maybe it's the lens in which I look at these things given my beat area for Design News, but it stuck me as interesting that predictive modeling and simulation endeavors are factoring so prominently into DOE funding. Now predictive modeling is different than the simulation (CAE) stuff we talk about here quite a bit. Any intel on what role exactly the predictive models are going to play in the work being done to advance lightweighting and new materials?
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
This month will mark the launch of the SpeedFoiler, a super-fast, ultra-lightweight foiling catamaran that can fly short distances over water faster than other foiling designs, in part because of its carbon composite materials.
