OS1728 Moderation of Dependence of Frictional Coefficient of C/C Composite on Temperature due to Addition of Glass Fibers into Carbon Precursor
Details
The purpose of this study is to prevent the reduction of frictional coefficient of C/C composites at low temperature to moderate the dependence of the frictional coefficient on the temperature condition. In this study, the char matrix of C/C composites was prepared from phenolic resin. The phenolic resin was modified with micro sized glass fibers referring the results by previous studies, in which friction coefficient had been improved by the addition of short glass fibers into some conventional friction materials. The results of frictional tests under various temperature conditions and observation of the frictional surface after the tests suggested that the reduction of frictional coefficient at low temperature was prevented due to the scratching with SiC particles which was fabricated in the body of C/C composites modified with micro sized glass fibers and the dependence of the frictional coefficient on the temperature condition was moderated.
