A Swiss aircraft project will advance composites technology for the aircraft industry by a factor of two to three, says Andre Borschberg, CEO of a company called Solar Impulse, which will launch its first test flight next year of the manned solar-powered airplane. I caught up with Borschberg on the floor of one of the close to 20 buildings at the sprawling K 2007 in Düsseldorf, Germany. “Its unusual, for example, to use high-modulus carbon fibers,” said Borshberg. Get this: the wing span on the final model will be 80 meters, the same as the Airbus A380, which weighs 560 metric tons. The craft Borshberg will help pilot around the globe in about 12 four years will weigh just two tons. It will be powered by the latest in electric motor technology. The solar panels will only provide enough electricity to light up a very large Christmas tree, requiring enormous effort to keep weight low. The planes will fly at night on battery power. Solvay Advanced Polymers of Alpharetta, GA is a development partner for the plane and is already well along on a shielded throttle housing.
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.
