Can IACMI propel us out of adolescence, into adulthood?

On Jan. 9, the US Department of Energy (DoE) announced that it will add US$70 million to the US$189 million already committed to the University of Tennessee’s Institute for Advanced Composites Manufacturing Innovation (IACMI) for composites R&D. CW's editor-in-chief Jeff Sloan asks, "What will come of this investment?"
