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.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
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.
