## On pyrolysis of a phenol-formaldehyde resin at temperatures up to 700°C there was no change in the infra-red spectrum below 300°C but above this temperature the hydroxyl absorption began to decrease. This and other changes indicated the formation of diphenyl ether type linkages between benxene

The pyrolysis of carbon/phenolic composites is a critical step in the manufacture of high temperature carbon/carbon components. Understanding the reaction kinetics of the pyrolysis reactions is essential for advancement in the processing of carbon/carbon materials. To increase the understanding of t
An X-ray diffraction study of the carbons which were prepared from phenolformaldehyde resin, 3-methylphenol-formaldehyde resin and 3 \* 54imethylphenol-formaldehyde resin all heat treated in the temperature range from 900 to 3000°C was carried out in order to find the relation between the graphitiza
The carbonization mechanism of phenol-formaldehyde resins has been studied by using three types of isotope-labelled resin, which hold (I) deuterium atoms in hydroxyl groups, (2) deuterium atoms in methylene groups, and (3) "C atoms in methylene groups, respectively. The resins were carbonized in vac
## Pyrolysis of composites prepared from a phenol-formaldehyde resin and carbon fibres (CFRC) or oxidized PAN fibres (OFRC) has been investigated up to 1270 K. Two temperature regions can be distinguished in the pyrolysis of the CFRC: below 770 K the carbon fibres hold the composite structure resi
The formation of impermeable glasslike carbon by thermal decomposition of 3-dimensionally cross-linked polyfurfuryl alcohol, phenolic resin, and mixtures thereof was found to be independent of the chemical structure of these resins. In each temperature range, pyrolysis products were obtained in whic
