Abstract


Effect of loading rate on strength of composite materials at high temperatures (up to 3300 K) Purpose. Placed in the task of obtaining experimental data in tension in one direction (σ1) carbon-carbon composite material (VVKM) at high temperatures (up to 3300K) and develop methods of transferring the experimental results in terms of loading at different speeds Design/methodology/approach. Using thermodynamic approach to determine the mechanical properties of the material and build tension chart "σ-ε". Findings. With the proposed method estimated constructed diagram is different in strength by only 10%

Keywords
