“…Thus, in order to meet the foaming conditions, in this case, the PR was chosen as additive to reduce the viscosity of precursor in the presence of catalyst MBSA. The process of co-carbonization reaction of PR and raw CTP was mentioned in our previous work [37,38]. Here, the content of catalyst MBSA in the reaction system was invariant (1 wt%) for all samples.…”

“…It only explains a minor part of the weight loss which is due to the gasification of carbon material. 60 This usually ends between 500 and 600°C depending on the precursor. Between 350 and 450°C, polycyclic hydrocarbons of about 10 cycles face condensation reaction and their size increase 61,62 .…”

“…Figure 9). 60 Figure 9: Phase formed during thermal treatment of pitch 63,62 From temperature over 700 °C and in all cases at 900 °C, aromatics are the mains molecules. Further temperature increase will mainly improve crystallinity, instead of aromaticity.…”

“…Heat resistance and the operating temperatures of polymer-based composites are limited by the heat resistance of matrix polymer. Carbon matrices obtained by pyrolysis of various polymer binders [13][14][15], coal tar [16][17][18] and petroleum [19][20][21] pitches have exceptionally high heat resistance. A direct approach in getting carbon matrices via classical carbonization is the rapid implementation of the pyrolysis process, which ends with the formation of char at temperatures of about 500-550 • C, followed by the formation of a carbon matrix at temperatures of 900-1700 • C. It is known that thermal degradation results in an increase in the given polymer material's thermal stability; however, at the same time, thermal degradation results in a decrease in the strength and deformation characteristics of materials [22][23][24].…”
