Iranian researchers at Shahr-e-Kord University succeeded in predicting the mechanical properties of nanocomposites through numerical methods and further improved these properties by utilizing carbon nanotubes.
"Composites strengthened by the carbon nanotubes have better mechanical properties compared to the ordinary composites. Such nanocomposites have many applications in various industries, especially aerospace industry," Dr Hossein Golestaniyan, member of the Scientific Board of Shahr-e-Kurd University, told Iran Nanotechnology Initiative Council.
According to him, the main reason for using numerical methods and models is the lack of laboratory facilities to synthesize nanocomposites and to measure their mechanical properties in Shahr-e-Kurd University.
Dr Golestaniyan explained about the results of the research, and said, "Carbon nanotubes are very effective for strengthening the polymeric bases. Taking into account the adhesion in the common phase between nanotubes and the base material, the results showed that the more the adhesion exists, the more the strengthening effects of carbon nanotube would be."
"In general, we concluded that the relative effect of carbon nanotubes on the mechanical properties of the base material is higher for the materials with lower elastic modules," he added.
Golestaniyan concluded that those nanocomposites can currently be used in aerospace industry as well as in the production of aero-structures due to their high price and unique characteristics.
