Abstract

PURPOSE:To improve mechanical strength, corrosion resistance and workability by binding a composite material to a carbon matrix in an amorphous state by re-baking after dipping in a solution consisting principally of a silicon-boron-based semi- inorganic polymer. CONSTITUTION:Synthetic resin is mixed with scaly graphite and the mixture is rolled into a sheet to orient scaly graphite in the thickness direction. Next, it is formed in the shape of a diaphragm and dipped in a solution consisting principally of a silicon-boron-based semi-inorganic polymer. Then, it is baked by heating in a nonoxidizable atmosphere to carbonize the synthetic resin, so that a carbon matrix composite material of scaly graphite will be formed.
