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.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
