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.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
