Title:
LIGHTWEIGHT ALUMINUM-BASED COMPOSITE MATERIAL IMPELLER FOR FLUID DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/131097
Kind Code:
A1
Abstract:
A lightweight aluminum-based composite impeller for a device driving a fluid such as a gas or a liquid, comprising a blade set (11) and a substrate (12), wherein the blade set (11) is prepared from an aluminum-based composite material, and the specific rigidity of the aluminum-based composite material is not less than 30 GPa/g/cm 3. The weight of the impeller is significantly reduced, and the specific rigidity of the aluminum-based composite material is not less than 30 GPa/g/cm 3, which is higher than that of an existing metal. Therefore, the blades on the light-weight aluminum-based composite material impeller are not prone to deformation under fluid pressure, thereby achieving good fluid driving performance while maintaining a light weight.
