The composite material designed by Affan Innovative Structures, based on Dow Chemical's Voraforce TF epoxy infusion systems, is being used in non-load-bearing structures. Its high-energy absorbance is important to help reduce damage in the earthquake-prone Middle East. (Source: Affan Innovative Structures)
Ann, social media, at least of the facebook kind, has already gotten old and become a worthless collection of features, as far as I am concerned. Really, it is more like "spewing data" as opposed to sharing information, and very little of communicating insights is done, from what I see. I would not miss it one speck if it were gone some morning.
The various online discussion groups are different by quite a bit, and I enjoy the physics papers weekly publication and discussions as well.
Ah, Chicago still feels warm to me, Cabe. But I know what you mean about steel. I think composites are still a mystery. We don't know yet whether they're going to catch on and we don't know the full range of applications we'll see with composites. It will be interesting.
William, corrosion usually refers to what happens when metal breaks down. Composites can certainly break down, but "corrosion" is not the correct term. They delaminate, fragment, and suffer environmental stress cracking, as we've discussed here: http://www.designnews.com/author.asp?section_id=1392&doc_id=238056 http://www.designnews.com/document.asp?doc_id=236816 http://www.designnews.com/author.asp?section_id=1365&doc_id=238200
Ann, actually, from what I have read, composites do corrode, but differently from metal.
The one other thing is that typically buildings are kept around a lot longer than aircraft or racecars, so that what happens after 30 years of weather matters on a building, while the race car is obsolete and the airplane is probably scrapped, or sold to the minor leagues.
Glad to see the reduction of wood use in architecture. But, I think that is a "no-brainer." A cow in a barn destroyed the wooden version of Chicago. Now, it's all rusty steel. Not a single fire since. Though, the city now has a cold feel to it.
William, I had the same question about damage, but I don't see why the wear problems would be much worse than what aircraft with carbon composite skins experience; in fact, they're probably not nearly as severe, since these buildings aren't speeding through the air and storms of hail, dust, and rain like planes do. Composites, of course, don't corrode like metals do.
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
