The Automotive composites Alliance is pushing thermoset plastic composites for a wide variety of applications in hybrid cars, including modules that contain the battery pack, electronic controller and wiring harness. In the US the modules are typically made of several metal stampings which are assembled. Use of composites could reduce the module to two pieces with major savings in weight as well as tooling investment. “Unlike metal, composites don’t conduct electricity, therefore providing an extra safety advantage,” says the Alliance report. “They also won’t corrode and allow integrated airflow cooling in the module’s tunnel, all adding to longer battery life.”
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.
