News that GE wants to sell its plastics business is of interest to design engineers. In the past 25 years, engineering plastics suppliers, led in part by GE Plastics, have been important developers of exciting new designs for plastics, such as instrument panels and various business machinery. Rising raw materials costs (oil-related, primarily) have reduced the profitability of the business and made it a weak performer for high-flying GE. This was surely a tough pill for the company to swallow because famous CEO Jack Welch cut his teeth at GE plastics after graduation as a chemical engineer from the University of Massachusetts.
One personal anecdote shows the role GE Plastics has played in design development. I was having dinner many years ago with a man named Uwe Wascher who was a VP for GE Plastics. After a few drinks, he recalled his role in the development of Xenoy as the first ever-bumper material for a European car. Wascher, who is German and was based in Europe, said he sold the OEM on polycarbonate before testing had been fully completed. PC (developed by GE’S Dan Fox about the same time Bayer also discovered the polymer) was used on some prototype models, and was damaged by gasoline spills because of its poor chemical resistance. Washer set up a major research skunk works in GE corporate office in Europe. The 24/7 push—because the model was close to production—led to development of a PC/PBT polyester alloy known as Xenoy. The rest is history.
Wascher left GE several years ago, and probably has PR people with him when he has dinner with reporters these days.
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.
