Design issues on the Boeing 787 Dreamliner get almost as much scrutiny as Tiger Woods pulling out of his driveway. The latest issue is the status of the much-discussed fix to the midsection of the composite fuselage.
Some composite material surrounding bolt holes delaminated during recent tests, but the issue isn’t expected to slow the first test flight of the Dreamliner. The delamination occurred in areas around metal plugs that are installed after exposure to liquid nitrogen. The bolts expand as they thaw.
A Boeing spokesperson said: “The freeze plug process is a standard repair we perform on both metallic and composite structure. We have extensive experience using these techniques. We have not seen any issues with these repairs that are inconsistent with our experience or the capability of these repair techniques.”
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
