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.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
