Use of carbon fiber-reinforced plastics (CFRP) in cars continues to advance. Audi and Voith GmbH announced a partnership to promote industrialization of fiber-reinforced materials, particularly through developing a highly automated process for high-volume automotive production.”Fiber-reinforced polymers offer weight and strength advantages, which we have already put to use in the Audi R8 and the Audi RS 3 Sportback, for instance,” says Rupert Stadler, chairman of Audi. Voith has been working for several years on the use of CFRP to light weight components in paper machines and in machine drives.
Audi has already made extensive use of other lightweight materials to make its cars more fuel efficient. These include aluminum, steel and magnesium.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
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.
