A thermoset resin as matrix precursor has been characterized by differential thermal analysis and thermal gravimetric analysis. Curing and carbonization cycle as well as the content of suitable solvent and cross-linking agent in the resin were modified. The effect of modified processing on the densification efficiency of the phenol-furfural-based carbon composite was investigated and the structure of the composite was examined by scanning electron microscopy (SEM). The microstructure of the three-dimensional phenol-furfural resin-based carbon composite made with the modified process was compared with those of the normally processed composite. The results showed that the modified process resulted in a relatively greater density with fewer impregnation cycles when compared to the normal process.
