At Sandia National Laboratories, an unusual thing has happened. Researchers 3D printed a massive mold for manufacturing wind turbine blades. The project is a collaboration with the leading manufacturing laboratory, Oak Ridge National Laboratory, and TPI Composites that aims to dramatically reduce the time and cost of developing new wind energy technology. Sandia has been
Purdue researchers have observed a way that the brittle nature of ceramics can be overcome as they sustain heavy loads, leading to more resilient structures such as aircraft engine blade coatings and dental implants. While inherently strong, most ceramics tend to fracture suddenly when just slightly strained under a load unless exposed to high temperatures.
“Everyone in the industry has been waiting for this discovery. This is a paradigm shift in the field of high-temperature oxidation. We are now establishing new principles for understanding the degradation mechanisms in this class of materials at very high temperatures.” Many current and future technologies require alloys that can withstand high temperatures without corroding.
