One of outcomes of the drive to reduce fuel consumption will be a major drive to composites. Boeing’s 787 Dreamliner will improve fuel efficiency 20 percent through use of composites in half of its structure. All of the material is coming, at least for now, from Toray Industries, the world’s largest supplier of PAN-based carbon fiber. Toray says demand for the material is growing at a 15 per cent annual rate, with much of the immediate push coming from the Boeing 787 Dreamliner. But Toray says a major demand developing from auto producers, which are already experimenting with high-tech thermoplastic composites. The carbon fiber matrices will also be used more in CNG tanks. Prices of the materials are soaring, and there have been reports of supply constraints. Toray is spending close to $1 billion now to boost capacity.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
