Abstract
Metal complexes are obtained by reacting furfurylamine with a metal carbonyl selected from the group consisting of tungsten carbonyl, molybdenum carbonyl and chromium carbonyl. Multi-cycle reimpregnation polymers are obtained by reacting one of these metal complexes with furfuryl alcohol. A carbon/carbon composite is formed by impregnating a carbon/carbon composite containing voids with said polymer and curing and carbonizing said polymer.
