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.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
Nearly all the products in this latest crop of new adhesives target electronic and other components for consumer electronics and automotive assemblies. Some are alternatives to liquid adhesives, others are liquids that cure faster, and several stick well to multiple substrate materials.
