The UAW-Ford 500 at Talladega Superspeedway on Oct. 5 will be the first restrictor-plate event for NASCAR’s Car of Tomorrow. Part of an overall program of new designs and materials, the restrictor plate is aimed at cutting engine power from 750 hp to approximately 430 hp. Drivers have resisted some of the innovations which are designed to improve safety. Dow Automotive is developing new energy management foam for the Car of Tomorrow (COT) Project that’s expected to be widely used next year. It’ll be placed between the roll cage bars and door panels. The energy of the impact is managed through a series of controlled reactions within the foam. The new foam is also said to reduce weight 50 percent compared to competitive foams. Installation errors (too close to the tailpipe) led to some melting and fuming problems in early trials.
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.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
