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 new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
