Considering a move to bioplastics? Consider the experience of John Deere, which is now in the eighth year of a program to use soybean and corn feedstocks that was not originally driven for green reasons. The biomaterials are used in combine panels, backhoe loader hoods, and tractor hoods. Greg McCunnn, who runs the project, says the materials must be cost competitive and must be a performance drop-in for petroleum-based plastics. Needless to say, significant supply chain work was involved, and included funding from the United Soybean Board. Ashland Specialty Chemicals developed polyester resins that include soy and corn feedstocks, while processors Ashley Industrial Molding and Budd (currently Continental Structural Plastics) worked on the molding side. There were also issues related to painting and mold release.
And it amounts to more than a hill of beans: each combine made with the compound uses 1.1 bushels of soybeans and 0.5 bushels of corn.
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.
