초록
In this study, carbon/phenol composites were prepared from carbon fiber preform and phenol resin by RTM(resin transfer molding) process. And changes in the properties of the composite according to the pre-treatment of phenol resin was mainly studied. RTM process conditions were deduced from viscosity and thermal analysis of phenol resin which were rheometer and thermogravimetric analyzer(TGA). RTM process was performed under various injection and molding temperature. Characterization of the prepared C/P composites were evaluated by various analyses. Morphology of composites was analyzed by Micro-CT(MCT), Mechanical properties of composites were measured through the flexural properties. As results, volatile impurities of phenol resin were effectively removed at resin pre-treatment temperature of 100℃and composite was sufficiently cured at molding temperature of 180℃.
