For composites users, the latest weapon in the war against
corrosion can be found on the World Wide Web. The Composite Polymers Division of
Ashland Specialty Chemical Company (Dublin, OH) has launched a "corrosion
resource center" at www.hetron.com to help
engineers pick the right resin for corrosive environments.
At the heart of the resource center is an on-line edition of the
company's Hetron and Aropol Resin Selection Guide. In addition to materials
property data, it compiles corrosion-resistance data for fiberglass reinforced
plastics in 1,800 chemical environments. The data in the guide has been culled
from field and laboratory (ASTM C581) studies of FRP performance. And because
the guide ties into the company's corrosion database, its information stays
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.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
