ORNL has developed a new hybrid additive manufacturing technique to create complex three-dimensional shapes like air foils and wind generator blades much more quickly.
Technologies are described directed to reducing weld additive part distortion with spot compressions integrated into the build process. The disclosed technologies can be used to make weld additive parts with potentially better geometrical accuracy.
ORNL researchers have developed a new method for producing thermoset foam insulation with improved processing and installation outcomes.
Complex protective casings and housings are necessary for many applications, including combustion chambers of gas turbines used in aerospace engines. Manufacturing these components from forging and/or casting as a whole is challenging, costly, and time-consuming.
The ID provides a solution approach for faster chemical processing and carbon functional grading from SiC to MC to provide a tougher carbon and CMC structure.
The solution proposed here is a modified carbon-based tile face that is mechanically combined with an insulative backing. The tile face is based on a material architecture to minimize weight and thermal conductivity while maximizing thermal stability.
Compliance in a part, work holding, or base plate is beneficial for certain processes, but detrimental for machining and material removal.
