DuPont is focusing development of its proprietary nanocomposite technology on a range of polymer matrices including polyester and polyamides. That was one of the announcements made by Nandan Rao, the technology director for performance materials during a press conference in Prague to discuss developments that will be shown at K 2007 in Düsseldorf this fall. At any given temperature, the modulus of nano-reinforced PET improves up to a maximum of 140° Celsius.What it means: use of the nano materials can reduce the amount of glass reinforcement and improve surface properties. Less glass reinforcement opens the door to reduced weight without sacrificing properties.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
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.
