含浸法による耐酸化性炭素繊維強化炭素複合材料の作製

抄録

The oxidation resistance of the C/C composite is low because all constituent material of the fiber and matrix in C/C composite consists of carbon. Therefore, the C/C composite material has some limits to the effective use of the other various excellent properties. The aim of this study was to give the resistance oxidation performance to the surface of C/C composite covered with SiB₆ by dipping process. SiB₆ powder was dispersed to a triethyleneglicol using the dipping process in order to coat this sample. The C/C composite sample was obtained with additional mass equal to about 2.5% of the total sample mass, and surface of its sample was coated with SiB₆ powder. The sample made by the oxidation experiment showed better resistance to oxidation in comparison with the C/C composite material without its process.
