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.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
