Composites are helping architects to make highly unusual curved and freeform shapes in large buildings in the Middle East, such as the Sidra Hospital under construction in Qatar on the Arabian peninsula. Roofing panels up to 15m to 25m (49 ft to 82 ft) long have been made with the material. (Source: Affan Innovative Structures)
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.
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?
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).
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.
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
The grab bag of plastic and rubber materials featured in this new product slideshow are aimed at lighting applications or automotive uses. The rest are for a wide variety of industries, including aerospace, oil & gas, RF and radar, automotive, building materials, and more.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
