Effect of processing parameters on the mechanical properties of carbonized phenolic resin

Dimensional changes of carbon fiber fabrics reinforced phenolic resin-based carbon/carbon composites during pyrolysis

“…Therefore, only less than 1% shrinkage in length and width was measured. On the other hand, the shrinkage in thickness could reach about 4% (average value at 1800 • C), although this value is still much less than 18% for pure phenolic resin carbonized at 1000 • C [13].…”

“…Since the transverse cracks are relatively perpendicular to the plane of the composite plate, the width of the transverse cracks will affect the length and width of the composites. Because the width of the transverse cracks increases with rising heat treatment temperature and the degree of shrinkage of phenolic resin became smaller at higher temperatures [13], the shrinkage in length and width decreased after reaching a maximum value at about 1600 • C.…”

“…It is known that dimensional changes take place when the phenolic resins are carbonized [13]; this applies also to phenolic resin-based C/C composites. Moreover, different types of cracks are formed during pyrolysis of two-dimensional C/C composites as a result of the shrinkage of resin matrices [14 -16].…”

Hardness and microstructure of carbon pellets from self‐adhesive pyropolymer prepared from acid and alkaline‐treated oil palm bunch

“…17,19 This is in contradiction with the data for the carbon samples from phenolic resin, which show that the sample density is higher after carbonization. 30 The decrease in the density of samples B and C after carbonization may be related to the fact that the treatment dissolved some of the components in the EFB samples and thus reduced the sample weight. However, the removal of these components may minimize the gas evolution during carbonization and may help the development of a better microstructure and stronger intermolecular cross-link within the solid phase of the sample, as indicated by the improvement in their hardness value due to the treatments.…”

Effect of Processing Variables on the Microstructure and Mechanical Properties of Microporous Carbon Materials

“…It is well known that the microstructure formed during the pyrolysis of pure resins has significant influence on the mechanical properties of glassy carbon materials [9][10][11]. The carbon produced by the pyrolysis of pure resins has porous networks with irregular pores.…”
