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)
How refreshing, Ann, to see these currvy buildings. I'd love to see more of this in the U.S. Is there any reason these materials are being used for buildings outside the U.S.? Is it because we're not building a lot of buildings these days
Even though these materials are being used in non-load-bearing applications, they must have considerable flexural strength. The structure in the secon slide looks like it would be subject to som high wind loading.
From the last paragraph it implies that Carbon Composites are still much more expensive than traditional steel or concrete processes. Would this factor be 2X or more? If so, then in the near future Carbon Composite techniques will still be limited to specialty applications where steel or concrete can't be used (unless a customer in a very wealthy location like Dubai wants to make a aesthetic statement and money is not the primary decision criteria).
Greg M Jung, you are correct their are still certain factors that keep us away from carbon fibre first one is the cost factor secondly there exist reliability issues.What if the crack or some damage occurs on particular object will it be repairable?
This is really cool to see, Ann. These buildings are much sexier than blocky buildings and it's interesting the composites are helping to make it possible. I was just in Sevilla, Spain, over the weekend and saw a similarly curved building that represents cutting-edge architecture for that city. (It really stood out from the other buildings in the city, which as you can imagine are quite old and ornate.) I don't know much about it but maybe now I will research it and find out if composites were used there, too. Maybe I missed it in the story, but does climate have anything to do with the use of composites? The climate in Sevilla is very dry and hot generally, just like the Middle East.
Yes, that occurred to me as well, Chuck. Even if the composites don't bear weight, they have weight of their own they need to support. One would guess this has been taken into consideration, including wind stress.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
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.
