The comparative investigation on the ablation transformations were carried out for the phenolformaldehyde resin composites on base of silica fabric and hollow corundum micro spheres. It was establish that the corundum micro spheres addition lead to the composite's heat conductivity reduction. As a result the temperature increased at the exposed spot, the linear erosion rate increased by the factor of 2,7 and the coking front line decreased by a factor of 2,3. In the issue the ablation gave rise to the high-temperature mechanical and chemical erosion and these last in turn triggered the number of the serial-parallel chemical reactions with both the composite material porosity increasing and the creation of the hightemperature reaction products mainly the silicon carbide.Ill.9.

<p class="TTPAbstract"><span lang="IN">The current study was aimed to prepare and to characterize a renewable silica-carbon nanocomposite from rice straw ashes. It was purposed also to study the use of the produced nanocomposite as reinforcing material in producing a synthetic wood made of three axial blend of treated rice straw powder, phenolfrmaldehyde resin, and the nanocomposite. A simple preparation route of nanocomposite silica-carbon from rice straw was formulated containing three steps, namely pretreating of rice straw, preparing of ultra fine amorphous black silica, and composing silica-carbon nanocomposite. The nanocomposite product was characterized using XRD, XRF, FTIR and SEM methods. The characterization results comfirmed that the silica-carbon nanocomposite was succesfully prepared. The utilizing of the nanocomposite as reinforce material in producing synthetic woods was conducted through hot-pressing some three axial blend compositions of the pretreated rice straw powder, phenolformaldehyde resin, and the nanocomposite. The synthetic wood products were characterized their physical and mechanical properties. As a result, the addition of the nanocomposite could improve the properties of the synthetic wood products.</span></p>
