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?
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
