Executive Summary
Impellers are used in numerous applications such as turbines or compressors. In some cases, the cost of the impellers are prohibitive and difficult to manufacture and incorporate into a system. MSU researchers have developed a new woven impeller design that is less expensive to produce, ideal for integrating other parts such as conductive and magnetic fibers, and motors.
Description of Technology
This technology introduces a woven impeller made from continuous fibers such as carbon, aramid, or glass, that forms both blades and a peripheral shroud as a single, seamless component using a resin-based "wetting weaving" process. The process enables complex blade shapes with lightweight, high strength, and cost efficiency. Additionally, an integrated electromagnetic fiber allows the impeller to serve as an electric motor rotor, creating a compact direct-drive system without traditional shafts or seals. The patent claims cover impeller designs, rotatable apparatus, chilling system, compressor, and methods of manufacturing.
