Boeing will soon be generating enormous amounts of carbon fiber scrap and is looking for a way to use it. According to a fascinating story reported by Plastics Today, about two-thirds of the carbon fiber purchased by Boeing as an aircraft construction material ends up as waste. It wasn’t clear why the percentage is so high. Presumably, the ratio will decline as Boeing and its partners gain more experience using the material. Much of the body of the Dreamliner 787 is made from carbon composites.
The commercial launch of the Dreamliner has been delayed about two years, but testing results are increasingly positive and full-scale production will require huge amounts of carbon fiber. The aircraft was originally expected to become commercial in May 2008, but the best hope now is for the planes to enter service by the end of this year. Boeing hopes to expand production to 10 per month in 2013. Another source of older carbon fiber will be parts from other planes that are being retired.
According to the report by Tony Deligio, Boeing is working with compounder RTP to qualify compounds using the recovered carbon fiber. An RTP Company glass fiber-reinforced PEEK compound is already specified for the hinge bracket assemblies (see photo below) of overhead storage compartments in Boeing 767 airplanes.
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
