摘要

Poly(phenol-formaldehyde resin)/carbon fiber composites with different ratios of graphene-Fe3O4 were manufactured through a molding press process. Fe3O4 was introduced into the graphene to avoid recombination of the layers. The effects of the amount of added graphene-Fe3O4 on the morphology, thermal conductivity, friction performance and thermal properties of the composites were investigated via scanning electron microscopy, thermal constants analysis, tribology and thermogravimetric tests. Scanning electron microscopy confirmed the enhanced friction surface of the composites and the combination of the resin with the fibers. The thermal conductivity measurements showed that the best results were achieved with 2.0 wt% graphene-Fe3O4. The friction coefficient and wear rate also decreased with the addition of graphene-Fe3O4 based on the tribological results.
