Many other thermoplastic and thermoset polymers such as polymethyl methacrylate [5], poly(vinyl chloride) [6], polylactide [7], polyarylate [8], phenol formaldehyde resin [9] are also subjected to carbonization during the production of carbon materials possessing improved performance properties. Some difference can be related to the nature of the fillers; so the moisture permeability of SiC-reinforced composites is lower than that of for T2 and T2-2 SiC-free compounds that do not contain SiC. [...]it can be concluded that the SiC-reinforced composites have a smaller volume of open porosity. [...]the SiC-reinforced composites have smaller values of CA, because SiC itself has a more hydrophilic nature than that of carbon. Since the NBR and its composites are not resistant to oxidizing chemicals [19], the effects of immersion in liquid chemicals are also a critical performance aspect of using the obtained composite materials. [...]the fillers used as well as high filling degrees (up to 300 PHR) mainly determine mechanical properties of the carbonized composites.
