Two years ago, Boeing was in the news because fastener supplies were causing production problems for the new Dreamliner 787 aircraft.
Today, the news is much brighter for the Dreamliner and its fastener supply. Aerospace fastener manufacturer Saturn Fasteners, an operation of Acument Global Technologies, announced it has received a 2009 Boeing Performance Excellence Award. Saturn Fasteners has provided Boeing with custom assembly products for its aircraft programs since its founding in 1989. The company’s statement did not specify particular Boeing programs, such as the Dreamliner.
Another interesting assembly development comes from Greene, Tweed & Co., which makes net shape thermoplastic carbon-reinforced brackets for aircraft applications. The brackets cut weight up to 80 percent compared to the steel or aluminum brackets they replace. It is not clear which programs the new composite brackets will be used on, but the Dreamliner would certainly seem to be a candidate. Boeing is looking for ways to cut weight on the Dreamliner, which at last unoffical report was 8 percent above design weight. The extra weight results in part from extra strengthening required to solve potential delamination problems. The problem takes cash out of Boeing’s pocket because the promised range of the 787 is cut by 10-15 percent. Boeing officials have said they are taking steps to reduce weight, but no specifics have been released yet. Potentially hundreds of the brackets could be used on a single aircraft. Greene, Tweed installed one ProFusion press last year, and is installing two more this year.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
