This work has developed a procedure for incorporating carbon nanotubes (CNT) on a phenol / epoxy matrix to be used as a carbon fiber composite. Performing for such oxidation of the NTC with the use of microwaves and their functionalization with 3aminopropyl-triethoxysilane, a coupling agent used between the resin and CNT. After processing, as a result of the addition of CNT, the resin obtained an increase in the glass transition temperature and an improvement in flexural strength and impact resistence. In the carbon fiber composite, hand lay-up prepared, where the phenol / epoxy and CNT was used as a matrix, we obtained the increase in the limit of tensile strength and impact resistance, confirmed by an analysis of variance with 95% confidence, showing efficacy in the treatment of CNT.
