Preparation of 3D orthogonal woven C-SiC composite and its characterization for thermo-mechanical properties

► 3D orthogonal C-SiC using LSI having uniform properties have been fabricated. ► CTE in all the direction varies from −0.5 × 10−6 to 0.9 × 10−6/°C over 25-1050 °C. ► Thermal diffusivity in all the direction varies from 37.0 to 7.0 mm2/s over 25-1200 °C. ► Mean flexural strength at room temperature in all the direction is about 190 MPa. ► After five thermal shocks, the residual flexural strength is about 112 MPa.
