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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
