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.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
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.
