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.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
The upcoming MD&M West and co-located shows in Anaheim next month will be host to a huge variety of technologies and special events like the Golden Mousetrap Awards. Here are five reasons for medtech professionals to attend.
Many of the new 3D printers and printing technologies in this slideshow are breaking some boundaries, whether it's build speed, new material types, density and quality of 3D-printed circuit board layers, or build volume in a hybrid printer. We also give some recent market statistics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
