Development of carbon-ceramic composites employing SiC and graphite as reinforcement with phenolic matrix

Efforts have been made for the development of carbon-ceramic composites utilizing silicon carbide (SiC) and graphite as reinforcement with phenolic powder as a matrix. These constituents were placed to ball milling for uniform particle size distribution at certain rpm speed. Subsequently, raw materials hot pressed, which compact raw materials in the desired shape under high pressure and high temperature, further carbonization proceeded. Using different composition ratios of the SiC-Pf and Graphite-Pf, the different type of composites have been fabricated and the behavior influenced by the reinforcement has been studied. Sophisticated instruments techniques like FTIR, SEM have been used to analyze the samples. A system with SiC(36gms) and Pf (24gms) is observed to be the best
