Opel is in the news almost weekly for financial reasons. But the German-based subsidiary of General Motors is also making some technical news. Opel joined with Recaro, a Tier II seat maker, and BASF to develop an all plastic car seat that eliminates the requirement for a steel frame.
The seats are low weight while offering high mechanical strength, good ergonomic properties and a sporty look. The seat pan is made of Ultramid B3ZG8, a very tough yet stiff PA6. Ultramid B3G10 SI is used in the large, free-standing backrest shell as well as in the crossbar. The insert for the backrest shell is made of Neopolen P 9225 K (EPP), an energy-absorbing foam that also covers edges and serves as a module carrier for motors and seat components such as the spinal column support.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
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.
