Based on the headlines, it may seem like aircraft construction is racing toward plastic composites, with little hope left for aluminum. Well, don’t tell that to the aluminum guys. As reported here previously, Alcoa has been developing new alloys, composites and designs. There’s another to report now: scientists at Delft University of Technology in the Netherlands have received a patent for a fiber metal laminate (FML) called CentrAl reinforced aluminum. The structure includes aluminum alloys, adhesives and poly-paraphenylene terephthalamide threads. It has better tensile strength than alloys, and also boasts good metal fatigue and damage tolerance characteristics. And get this: a wing made from the composite would be one-fifth lighter than a wing made from plastic composites. The new composite has thicker laminate layers than the Glare used in the Airbus A380. The Air Force may use the material to replace wing sections in C130s. Development partners are Alcoa and GTM Advanced Structures.
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
