Toyota Motors and Mitsubishi Motors are pushing the envelope on lightweight car design with new concept cars introduced at the Tokyo Motor Show this week. The Toyota 1/X hybrid weighs 67 per cent less than Prius due to its use of carbon fiber composites in its body, yet has more interior space. Composites previously used in auto car bodies have much heavier glass reinforcement. Carbon fiber reinforced composites, also widely used in the Boeing 787 Dreamliner, weigh 40 percent less than glass-reinforced composites. Toray, the world’s leading supplier of carbon fiber prepregs, is reportedly studying a new production plant just for automotive demand. The Mitsubishi i-MiEV (electric vehicle) uses an aluminum suspension and frame. It weighs just one-third what a steel suspension and frame weighs.
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.
