An environmentally friendly route to prepare hierarchical carbon/carbon–SiC composites by carbothermal reduction

Hierarchical carbon/carbon–SiC composites have been prepared by a carbothermal reduction process using impregnated silica as a precursor and 3D needle-punched C/C composites as templates at 1450 °C. Dense SiC layers surrounding the pyrocarbon were synthesized by further heat-treatments at 1600 °C. T...
