Scientists from Tomsk Polytechnic University, in collaboration with foreign experts, have proposed an innovative approach to creating ceramic composites that promise to become key materials in the aerospace and transportation industries.
As reported by the Ministry of Science and Higher Education of the Russian Federation, preceramic paper of complex composition, supplemented with carbide and oxide powder fillers, was used for the first time in the production process. Research has shown that by varying the ratios of these components, it is possible to precisely control the characteristics of the material, including strength, porosity, and other physical and mechanical properties.
The approach opens up prospects for the manufacture of structural elements that are complex in structure and shape, designed to operate in harsh conditions of high temperatures and loads. For the first time, specialists synthesized composite materials based on preceramic papers using titanium carboaluminide and aluminum oxide by spark plasma sintering.
During experiments at a temperature of 1150 degrees Celsius, a dense composite with a 30 percent content of aluminum oxide was obtained, demonstrating increased strength and hardness.
