Abstract

Abstract

The joining of C_f / SiC composites with preceramic silicone resin (SR) at high temperature was studied.The influences of the curing and pyrolysis process of silicone resin and those of the inert and active fillers were especially discussed. The result s show that the curing process of SR was accomplished by Si —OH. An appropriateamount of inert filler SiC (5 % , mass f raction) or active filler nano-Al/ Si powder is good for the joining of C_f / SiCcomposites.
