             abstract = "Glassy carbon can be manufactured practically without pores, named 
                         Monolithic Vitreous Carbon (MVC) or presenting up to 98% in 
                         transport pore volume, foam form, denominated Reticulated Vitreous 
                         Carbon (RVC). The glassy carbon processing is affected by some 
                         processing parameters, among them it can be cited the resin 
                         viscosity. The present work involves the optimization of RVC 
                         manufacture by monitoring the polyurethane (PU) foam impregnation 
                         with furfuryl alcohol resin with different viscosity values, which 
                         were obtained by dilution of the resin with different amounts of 
                         furfuryl alcohol. The resin samples used in the PU impregnation 
                         were characterized by thermal and rheological analyses. These 
                         results were correlated with scanning electron microscopy 
                         observations and compression test results of the impregnated 
                         polyurethane foam. The results show that the rheological behavior 
                         of the resin has significant influence on the polymerization step, 
                         affecting the homogeneity of impregnated foam and, consequently, 
                         its final properties, mainly the mechanical one. The impregnated 
                         foam prepared with the furfuryl alcohol resin diluted with 10% of 
                         furfuryl alcohol (eta = 11.4 Pa s) showed higher compression 
                         values (0.26 MPa).",
