Engineering Materials

Engineering materials is a discussion led by Design News Contributing Materials Editor Doug Smock on important new developments and applications that affect mechanical design. Metals covered include all types of steel and nonferrous metals, in all shapes. Resins covered include nylons, polycarbonates, polysulfides, polyimides, and polybutylene terephthalate (PBT). Other materials covered include ceramics and rubber. Topics covered include materials enhancement, new applications, process technology, tooling, sustainability, and economic issues. Posts will include latest news from global events such as K 2007, the Alliance of Plastics Processors Annual Conference, the National Plastics Exposition, and the annual technical conference (ANTEC) of the Society of Plastics Engineers.

Bush Goes green

Like it or not, design engineers need to get prepared for more environmentally oriented requirements. The newest evidence is an executive order from President George W. Bush that ramps by green requirements for the federal government. One of the six parts of the new order requires federal agencies to improve energy efficiency and reduce greenhouse gas emissions 3% annually through the end of fiscal year 2015. President Bush also wants agency acquisitions to reflect sustainable environmental practices, including acquisition of biobased, environmentally preferable, energy-efficient, water-efficient, and recycled-content products, and use of paper of at least 30% post-consumer fiber content. The requirement on bio-based materials is interesting. Design News plans to look intensively at the potential of bio-based polymers for engineering applications in the April 30 issue. Stay tuned.
