Abstract : Carbon-carbon composites of acceptable shrinkage and with negligible voids are prepared in a single casting step from acetylene-terminated Schiff's base monomers by melting a selected monomer, polymerizing it within a mold to form a green casting, and heating the casting to a carbonizing temperature. Blends of monomers may be used. Graphite may be admixed with the melted monomer to form a slurry before molding. Graphite in the form of woven graphite fiber may alternatively be positioned within the mold before the melted monomer is added thereto.
