1. Oil soared to $147 a barrel in July and then plunged to less than $40 at the end of the year, affecting prices of plastics and other hydrocarbon-based chemicals.
2. The financial crisis coupled with declining sales walloped materials and assembly companies across the board, with the automotive supply chain particularly affected.
3. Fastener problems continued to plague the Dreamliner. Poorly worded engineering specifications forced Boeing to replace as many as 8,000 fasteners on 12 Dreamliners being assembled.
4. American companies continued to divest plastics and chemical assets due to poor profitability. One of the biggest deals, a partnership between Dow and Kuwait, unwound at the end of 2008.
5. Growth (albeit slow) of green materials design. A handful of American engineers embraced green materials, led by an aggressive Herman Miller program. Notably absent from the green engineering revolution have been the Big Three.
6. Strong demand from China put pressure on stainless and other metals prices. In the second half, of 2008, metals’ prices crashed.
7. Carbon fiber emerged as a more serious engineering material, driven in part by a military requirement for lighter weight and greater strength,
8. Crash-resistant, structural adhesives emerged as an important tool for automotive weight reduction.
9. Innovative materials solutions made possible one of America’s more successful science explorations in space.
10. American manufacturers continued to adapt with innovative new designs.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
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.
