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.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
