Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The effect of carbon nanofiber dispersion in phenolic resins/carbon fabric composites was investigated. The dispersion efficiency in different systems and conditions was studied and the effect of nanofiber concentration on the properties determined. Carbon nanomaterial incorporation influences the mechanical properties of the composites and gives better thermal stability. Nanofiber dispersion shows better adhesion of phenolic resin to the fabric under fracture surface study.
