摘要: 本文从C/C复合材料的基体入手,研究了基体沥青、焦炭中添加氧化物的工艺条件及其在复合材料中的作用.结果表明,添加氧化物对基体改性,不仅能提高C/C复合材料的高温抗氧化性,也能对其它性能带来很大影响.只要控制适当的工艺条件,就可以得到高性能的C/C复合材料.Abstract: 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.
