Abstract :
Phenolic resins have excellent dimensional, thermal, chemical resistance and corrosion properties. Also, volatile substances produced during thermal degradation of this resin have low toxicity and, in addition, high coal tar. In this study, samples of phenolic resins were prepared with carbon fiber and nanoparticles of graphene. Different amounts of graphene (0.5%, 1%, 2% and 3%) were fed into 50% wt. Phenolic and ethanol resin by ultrasound for 10 minutes with 60% power. Subsequently, hybrid composites containing 50% carbon fiber were prepared by hand lamination and the baking process was carried out at a temperature of 120 ° C, 120 bar with hot pressing. The morphology and mechanical properties of nanocomposites prepared by SEM and three-point bending were studied and the results were compared. By adding 1% graphene weight to the composite, the modulus and flexural strength of the samples increased by 19.5% (GPa2 / 38) and 7.7% (MPa471) respectively. The shear strength of the sample containing 1% graphene graphene was 23% higher than the pure sample. The thermal resistance of the phenolic / graphene resin composites showed a significant increase compared to pure resin. For example, in samples containing 1% graphene, the observed increase in T5, T10 and Td, max was 12, 30 and C5, respectively.
