Abstract

In the present paper, the silica-phenolic composite (S-Ph) composites with different amount of B₄C were prepared, and the ablation tests of these composites were carried out using oxygen-acetylene jet. The ablation process was systematically investigated. The addition of B₄C with appropriate amount can efficiently improve the ablation resistance of S-Ph. The results showed that S-Ph containing B₄C powder of 2 wt.% exhibited the lowest linear and mass ablation rate. The influence mechanism for the results was analyzed deeply. The surface morphologies, phase composition, density and thermal conductivity of composites were characterized using a scanning electron microscope (SEM), X-Ray Diffraction (XRD), Archimedes method, and thermal conductivity meter, respectively. The present investigation will provide a theoretical basis for the preparation of the ablation resistant material.
