Abstract

Ablation rate and thermal conductivity coefficient for phenol formaldehyde type resole resin reinforced with single well carbon nanotubes (SWCNTs) and porcelain have been studied via oxy–acetylene flame and Lee’s disc, techniques respectively. Thermal conductivity results show, that the values increase progressively by succession of volume fraction of SWCNTs. Ablation rate behaves inversely, where it drops at high volume fraction of SWCNTs. Simulation of thermal conductivity results, which are calculated according to microstructures model and when we compared it, with the experimental results, it can be observed, that the experimental results, were located in between the parallel direction values and random direction values for SWCNTs, with respect to heat flux direction. Ablation simulation results values coming higher than experimental results values, this could be explained, as the interface affect of nanocomposites, which had high strength and strong bond force.
