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.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
