纳米SiO2对先驱体浸渍裂解法制备SiCf/SiC复合材料力学性能的影响
Abstract:
以纳米SiO2为填料，采用先驱体浸渍裂解法制备2.5D-SiCf/SiC(D为维数，SiCf为SiC纤维)复合材料，研究了前驱液中纳米SiO2含量对复合材料力学性能的影响。结果表明，纳米SiO2的添加能有效抑制先驱体裂解过程中的体积收缩，提高致密度，但过量引入易导致浸渍液黏度过高，浸渍效率降低。纳米SiO2含量对材料力学性能有较大影响，添加纳米SiO2后材料的抗弯强度和断裂韧性均高于没有添加的样品，材料抗弯强度随纳米SiO2含量的增加先增大后降低。当浸渍液中纳米SiO2含量为6%时，复合材料具有优异的力学性能，抗弯强度达到211.1MPa。
