Iran produces nanocoatings for protecting aircraft bodies

Teharn, Jan 25, IRNA - Iranian researchers from Malek-Ashtar University of Technology, Shahin Shahr branch, Isfahan Province, produced special nanostructured coatings that can be used in aircraft bodies as a protection against heat.

The advantage of such coatings over normal coatings is their ultra lightweight. The research has been conducted on a laboratorial scale and the results can be applied in aerospace systems and sustainable energies, Mehr News
Agency said.

Coatings were synthesized in this research using magnetic nanoporous pigments made of iron oxide, and their application in the protection of aircraft bodies was assessed in a number of tests.

Based on the results, magnetic nanoporous pigments synthesized in this research have appropriate structure. They have better light sorption to emission ratio than conventional industrial pigments or even carbon black. In other words, the ratio in the synthesized sample is closer to one compared to that in usual samples; therefore, such products are great options for use in the production of thermal coatings in aircrafts.

According to the researchers, weight is an important parameter in designing aircrafts and aerospace systems. In this research, the weight of pigment is lowered due to nanoporous pigments.

This finally results in a decrease in the weight of the final system. In addition, the concentration of pigment used in the structure is less than the critical volume concentration of the pigment because of the nanopores in the structure. Therefore, a better performance of the coating has been observed in general tests such as abrasion, adhesion and bending tests.

The research findings can be used in low-orbit space systems, solar collectors and energy production sources.
