※ SiC/C composite values show both of the "SiC/C composite layer" and "substrate(+impregnation)".
※ SiC/C composite thermal durability shows that of the "substrate(+impregnation)".
※ Measurement temperature range for the coefficient of thermal expansion is :
a) 350〜450℃　　b) 50〜150℃　　and others: 100〜200℃
※ Unit conversion: MPa=kgf/cm² ×0.098、 GPa=kgf/mm² ×0.0098、 W/(m･K)=kcal/h･m・℃ ×1.16
