It’s amazing to consider the long-term potential of carbon nanotubes as a polymer reinforcement if major issues (cost and health concerns) can be overcome. Research reveals the possibility of cross-linking CNT molecules prior to incorporation in a polymer matrix to form a super composite with a tensile strength of 20 million psi. Single-walled nanotubes exhibit unique electric properties and may be used for miniaturizing electronics beyond the micro electromechanical scale. Big producers are placing major bets on the technology. In Japan, Showa Denko is building a 400 million metric tons per year production plant. In Germany, Bayer is building a 200 million metric tons per year plant. They’re betting they can dramatically reduce the cost of CNTs which had been in the stratosphere as a pilot scale product, say $40,000 per pound. Multiwall nanotubes are down to $50 to $70 per pound now. Prices will drop as new plants come on line. Health issues must also be addressed.
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.
