Fracture toughness of the material for aircraft construction is increased by 1.5 times19 августа 2020 года
National University of Science and Technology MISiS (NUST MISIS) has announced scientists have found a way to increase the fracture toughness of silicon carbide by 1.5 times, the company said.
The solution is a structural material for the production of refractory parts, achieved due to the formation of reinforcing nanofibers in the structure.
In the future, the technology will expand the scope of silicon carbide application as a structural and refractory material, including for the aircraft construction. Articles about the development have been published in Ceramics International and Materials.
Scientists from NUST MISIS have found a way to improve sintering ability and increase the flexural strength and fracture toughness of silicon carbide ceramics by forming reinforcing nanofibers in it using the technology of self-propagating high-temperature synthesis.
