Controlling the Si/C ratio in SiC matrix based on the modified polymethysilane for C/C–SiC composites with enhanced mechanical properties

Fabricating SiC matrix with controllable Si/C ratio for C/C–SiC composites via precursor infiltration and pyrolysis is difficult to realize due to the absence of suitable precursors. Here, SiC precursors with Si-rich (Si/C = 1.23), near-stoichiometric (Si/C = 1.01), and C-rich (Si/C = 0.88) pyrolyze...
