EFFECT OF MATRIX MODIFICATION ON THE PROPERTIES OF CARBON/CARBON COMPOSITE (Ⅰ)

Starting from the matrix material of Carbon/Carbon composite,prosessing conditions and effects of the modified matrix containingpitch and coke doped with oxides have been investigated.Results show that matrix modification with the oxide dopants not only improves the oxidation resistance,but also affects the properties of the Carbon/Carbon composi to.High performance Carbon/Carbon composite can be obtained so long as the procedure conditions are appropriately controlled.
