3D Woven Lattices as Multi-functional Heat Exchanger

Unmet NeedPorous materials are a widely used heat exchanger for common household items such as radiators and refrigerators. However, these materials are typically focused on optimizing at most one or two physical/chemical properties (heat transfer, fluidic permeability, electrical conductivity, etc.). As a result, these materials tend to underperform...

3D Lattice Weaves with Tailored Damping Properties

Unmet Need Vibrations that occur within high speed rotary devices, such as turbines, can lead to excessive wear, fatigue, or failure. As a result, technologies to reduce vibrations within these components may result in substantial savings. Although polymeric materials typically offer excellent damping properties, they are not feasible in high temperature...
