An interesting design innovation at K 2010 is an electrically conductive plastic compound from A. Schulman being used by a Finnish lighting manufacturer. Copper and tin are loaded at a very high level (60 and 25 percent respectively) in nylon 6. The tin acts like a solder connecting the copper fibers. “The conductivity of the compound is 1,000 times better than the next most conductive plastic compound available (plastic loaded with steel fibers),” says Thilo Stier, innovation manager for A. Schulman. The first production part is a light made by Hella.
The production process for the light is a great story. First, the ABS plate and the PMMA (acrylic) reflector are injection molded in a three-component process. The electrical resistor, diodes, LED and contact pins for the plug are inserted and connected with the new conductive compound, which is called Schulatec TinCo 50. The ABS-coated reflector is then mounted to ensure watertight encapsulation.
Stier says the material is good for housings and lighting applications.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
