Nice story, Ann. Did they say which underhood components are being built from composites? In an earlier post, you mentioned that plastics are being used in some kind of EV battery partitions. Is this a trend we can expect to see going forward?

In aerospace, the parallel is military aircraft developing technology that can then be used, eventually, by commercial aircraft. The poster child technology example here is carbon fiber composites.

Good point on the bleeding-edge race cars, Ann. Chuck's recent Indy story -- and the comments that followed (http://www.designnews.com/document.asp?doc_id=243839&itc=dn_analysis_element&) -- discussed how GM has used racing engines to help develop its production engines.

  Flax isn't like glass properties at all.  And I see little impact from fiberglass unless anyone has a sand shortage.  Considering the water, land, etc needed to grow flax and gathering, processing it is likely to be more than processing sand into FG.  Far less if one uses concentrated solar power.

If they wanted to get the best from flax it shouldn't have been woven.

The Epoxies I use are mostly made from fat and the cleaner is vinegar, water if not to far into curing.  I've used this combo for 40 yrs now not because it's green but because it's far less toxic to my fair skin.

naperlou is right: many leading-edge, and even bleeding-edge, technologies are used first in race cars before automakers decide to work with suppliers to adapt them to commercial applications. It's a free test-drive for the commercial automakers, as far as stress testing goes.

Beth, Much of what they do has commercial applicability: at some level, cars are cars. Major car makers have used engineering-grade plastics for under-hood applications, including bioplastics, although not recycled or bio-based composites. Tata Toyo, an Indian manufacturer of under-the-hood heat exchange parts, traded its specialty nylon materials] for DuPont's Zytel PLUS nylon for three hot-side and cold-side charge air coolers under the hood in the vehicle's engine compartment.

for use in four different vehicles, in passenger cars, utility vehicles, and light commercial vehicles, of an undisclosed major Indian automotive OEM. Zytel RS (renewably sourced) nylon has been chosen by Hutchinson SRL for diesel and biodiesel fuel lines.

Other under-hood plastic parts include engine components. For example, Ford Motor Company reportedly uses high-temperature thermoplastics in its 3.5-liter V-6 EcoBoost engine for the F-150 truck, including key components like the cam cover, ducts, hoses and engine cover.

Beth, the race car industry often leads the way in introducing new concepts to the driving public.  That's why many large manufacturers have their own race teams and often support independent race teams.  These guys can try things that are not used in production.  The stresses of the race circuit ensure that they are doing things that will work (or they will find out quickly what does not).  Lola has been around for a long time.  They build prototype cars and innovate constantly.  Some of the innovations in racing from safety equipment and designs to aerodynamics got their start in racing.  So, this is an interesting development with the novel composites they are using.  We might see something like it in our cars soon.

Any possibility of commercial applicability?

It's amazing to me how much the race car industry pushes the envelope in terms of engineering technology, both green and otherwise. I know these are typically one-off or short production run implementations, but how much of what these guys do actually has commercial applicability?

The phablet wars continue. Today we welcome the Nexus 6 -- a joint collaboration between Google and Motorola.
According to a study by the National Institute of Standards and Technology, one of the factors in the collapse of the original World Trade Center towers on Sept. 11, 2001, was the reduction in the yield strength of the steel reinforcement as a result of the high temperatures of the fire and the loss of thermal insulation.

Robots are getting more agile and automation systems are becoming more complex. Yet the most impressive development in robotics and automation is increased intelligence. Machines in automation are increasingly able to analyze huge amounts of data. They are often able to see, speak, even imitate patterns of human thinking. Researchers at European Automation call this deep learning.
