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.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
