Chuck, I'd bet you're right on that one, at least for the materials in the Lola car. Other plastics have been used successfully in underhood-apps for non-EVs, as I mentioned in my first comment in this article thread. I'd be interested to know just what the actual average heat differences are. Meanwhile, I do know that internal combustion engines are getting hotter: several different materials and fastener companies have mentioned this trend.
That makes sense, Ann. Composites would not equal stealth technology when it comes to keeping the military technology secret. I wonder, though, whether the military shares the same values as the commercial industries when it comes to energy or economic savings. Given the $200 wrench and cost-plus contracts, probably not.
Ann, I wonder if these materials are better-suited to EV underhood applications than to internal combustion cars. Obviously, the underhood heat is much less because of the efficiency of electric powertrains.
I understand your thought process about the proprietary nature of military technology, but I suspect it's somewhat different with certain materials classes, such as composites. For one thing, commercial aircraft production is surprisingly complex. For composites, there are fiber makers, prepreg makers, sometimes separate composite makers that mold these into components, and then another level or two of structural suppliers before you get to the actual Boeings. There's also a lot of commercial R&D going on, at least in Europe, and now more in the US. In any case, composites per se are not a secret sauce for military aircraft apps, they're more like a basic ingredient. You know, like those $200 wrenches.
Thanks, Ann. I would guess that any development a company like Boeing completes on behalf the military would also be available for the company's commercial development. But maybe not. Could be there are proprietary military developments that would have to be shielded from commercial development.
Rob, I don't know of a formal procedure as such, but some aircraft makers, such as Boeing, manufacture both military and commercial planes, and many aerospace components and composites suppliers address both military and commercial markets.
Chuck, there was no detail at all about which under-hood components are being built with these recycled or bio-based composites. Umeco, the materials supplier, made the announcement, so I suspect they were under an NDA. This does look like a trend, meaning, the use of plastics in under-hood applications. As I mention in a reply to Beth below, it's already happened elsewhere. That said, this looks like the first use of composites in under-hood apps, at least AFAIK.
Ann, do you know if the military has a formal procedure for sharing technology with the commercial aerospace industry? Are industry engineers involved with military suppliers the way the automotive engineers are involved with Indy cars?
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
