| Abstract: | Carbon foams fall in the class of porous, cellular high
temperature non-metallic materials with interconnected porosity. In present
work, carbon foams have been prepared using commercially available polymeric
foams as templates and thermosetting phenolic resin as carbon source. The
prepared preform has been carbonized at different temperatures up to 1400°C in inert atmosphere to form carbon foam
with interconnected porosity. The removal of volatiles at different
temperatures has been studied using FTIR.
The effect of heat treatment temperature on density and volume shrinkage
has been studied. Thermal stability of carbon foam has been examined by TGA.
The porosity of carbon foam has been measured using water porosity and kerosene
porosity. Surface morphological studies have been carried out using SEM, which
showed that the pores are uniformly distributed and highly interconnected
throughout the structure. Compressive strength of the foam has been found to
increase with heat treatment temperature. |
