The Chevy Volt got big headlines at the Detroit Auto Show because of its electric power train. There was a tons of news in the materials as well. The materials used in a high-tech composite hood are made from regenerated plastic bottle scrap. In a proprietary GE Plastics process, bottles are reduced to their chemical constituents, which are then recovered for the manufacture of Xenoy iQ resins, which were first announced last July. As a result, there is no sacrifice in physical properties of the material, as can be the case with recycle resins. Denso, a Tier One automotive supplier, based in Kariya, Japan, has been validating 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.
