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.
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.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
