When will Airbus shift to an all-composite fuselage? Could it still happen for the A350? Those are burning questions as Boeing’s 787 Dreamliner continues to sell at a torrid pace. According to the Wall Street Journal, Boeing’s order book for the Dreamliner is moving past 600, while Airbus has less than 148 “less-firm” orders for the A350. The 787 has many advantages: it’s more fuel efficient, easier to maintain and more comfortable than A350. Airbus has been tweaking the design in an effort to catch up. A new variant, dubbed the A350XWB, will have a composite main fuselage skin on an Al/Al-Li frame. Even that could change, however, to an all-composite fuselage. Each shift pushes back the effective service dates for the flagging A350. The Dreamliner probably will have at least a five-year head start.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
NASA's JPL and Caltech have achieved the mind-boggling feat of 3D printing multiple metals in a single end-part, grading from one alloy to another. They've also developed a method for combining metals with carbon fiber composites in end-production parts.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
