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.”
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.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
