Satbayev University has developed a technology for using fiber-reinforced concrete in mechanical engineering

As part of “Zhas Galym” grant funding competition, young scientists from Satbayev University produced a prototype centrifugal pump housing made of composite materials without the use of metal. Traditional metal pump housings are highly durable, but they are characterized by significant weight, complexity of manufacture and high vibration levels.

As part of "Manufacturing technology of the carbon fiber pump body" project, Akzharkyn Igbayeva, senior lecturer at Technological machines and gas turbine installations department, conducted a complex of experimental and technological work in Satbayev University laboratories to elaborate new materials for mechanical engineering.

The conducted studies have shown that fibrocrete pump housings are highly resistant to dynamic loads, corrosion resistance and potentially longer service life compared to traditional metal analogues.

"The use of fiber-reinforced concrete in machine body parts makes it possible to significantly reduce vibrations and noise, increase the operational stability of components and simplify manufacturing technology. During the research, a technology for molding and curing the material was developed, and a centrifugal pump housing was manufactured that meets the requirements for strength and geometric accuracy," said PhD Akzharkyn Igbayeva.

The developed technology can be applied in mechanical engineering, mining and metallurgical industry, transport engineering, as well as in other industries where centrifugal pumps are employed and their performance needs to be improved.
