Study of options and mechanism was carried out through cooperation with related domestic units by means of advantage complementation.Based on the theory and experiments,the optimal composition of doped graphite and C/C composite with high strength,high thermal conductivity and low sputtering yield.The thermal conductivity of doped graphite was four times higher,and the chemical sputtering yield was lowered at one order of magnitute. In addition, radiation enhanced sublimation and temperature desorption spectrum are also improved.Comprehensive property of anti-plasma radiation was also enhanced ,leading to no cracks observed after 100-odd times of plasma charging for new multi-element doped carbon-base materials by contrast with pure C/C materials.
