An aluminum alloy designated 7085 developed by Alcoa is getting a foothold in tough aircraft and military applications.
The first application of 7085 was for large die forgings on the Airbus A380 wing spars. Higher zinc along with reduced copper and magnesium content give the aluminum alloy excellent strength and high fracture toughness. It’s used in the Boeing Dreamliner for wing spars and engine pylons. It’s also being evaluated for thick structural parts, such as blast shields, on military vehicles.
Engineers shifted from titanium to 7085 for large forgings that form the center section of the bulkhead of the multinational Joint Strike Fighter’s F-35B variant for the US Marines and Royal Navy. Reason: To save weight. Titanium is 60 percent more dense than the aluminum alloy.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
