Abstract

The thermosetting resin having 94 wt% of a high ceramic yield, MSP (-Si (C₆H₅)-C≡C-C₆H₄-C≡C-), was hybridized with silica by a Sol-Gel method. The hybrids were shaped into pale yellow transparent tablets by casting. The obtained tablets kept their shape during the pyrolysis up to 1273K without macroscopic cracks. By the hybridization with silica, the obtained materials after the pyrolysis shows higherresistance to the oxidation as comparedwith the materials merely derived from MSP. The dense silica layer formation on the surfaces played a role in increasing the oxidation resistance.
