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.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
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.
