It was apparent at the recent Great Designs in Steel seminar that steel plans on stealing a page or two from the plastics’ playbook in the key automotive battleground. Steel has several advantages to start with. The manufacturing infrastructure to make steel parts exists, and in fact represents a significant capital investment. Steel also has a strong recycling track record (to say nothing of performance). It seems intuitive that the high gas prices will kick start already existing efforts to reduce weight of cars. But not so fast. New grades of steel reduce weight, and also play into the trend to boost safety performance, particularly for the sides and rear of vehicles. For example an ultra high strength steel (boron-alloyed 22 MnB5) cuts 2 kg for a side crash panel in BMW’s new X6 Sports Activity Coupe. The seven-passenger Acura MDX body structure contains 56 percent high-strength steels, including several new advanced grades. It may surprise some, but some of these new grades are significantly more formable than your father’s steel, allowing creation of complex shapes previously only possible with plastic.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
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.
