The materials wars in the aircraft industry are heating up. Allegheny Technologies Inc. introduced its new titanium ATI 425 Alloy to the commercial aerospace industry at this year’s Farnborough International Air Show, held near London, UK. The Company’s display featured several products made from the new alloy including continuously cold-rolled titanium sheet, formed plate, and prototype aerospace fasteners.
Alcan launched a new lightweight aluminum alloy at the air show as Boeing flew in a composite-bodied Dreamliner 787 in its international air show debut.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
