摘要
四种用于制备炭／炭（C／C）复合材料的预制体，即1K发布叠层坯体（1#坯体），3K发布叠层坯体（4#坯体），发市+炭纸叠层坯体（2#坯体），特殊炭毡+发布叠层坯体（3#坯本），并探索了预制体结构对C／C复合材料力学性能影响．研究表明：用1#坯体制备的C／C复合材料弯曲强度最高，2#坏体制备的材料弯曲强度最低，随著炭纤维（CF）体积含量的增加，用四种坯体制备的材料弯曲强度增大。确定了弯曲强度的优化配方．
Four kinds of preforms used for carbon/carbon (C/C) composites,namely preforms by folded 1K carbon cloth (1#), 3K carbon cloth (4#),carbon clothf carbon paper (2#) and special carbon felt + carbon cloth (3#) were designed in this research. The effect of preform structure on mechanical properties of C/C composites was explored. The results showed that the flexural strength of C/C composites made ftom 1# preform is maximum,that of composites made from 2# preform is minimal. The flexural strength of C/C composites from four kinds of preforms increase as the volume ftaction of carbon fibre in pre forms raises. The optimum composition of C/C composites for flexural strength was determined.
