WebPhenolic resin chars when heated to temperatures greater than 480°F (250°C). This process continues at very high temperatures greater than 1,000°F (>500°C), until the resin completely converts to amorphous carbon. This characteristic contributes to the unique ablative properties of phenolic resins. WebJan 1, 1987 · Other properties, such as the linear expansion coefficient and elastic moduli of phenolic foam and glassy carbon, were adopted from studies by Gibson and Ashby [25]. Also, the effective heat capacity and thermal diffusivity of glassy carbon were either measured or adopted from previous studies of Mottram et al. [26,27].
