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.
Claims4
A carbon/carbon composite prepared by impregnating a carbon/carbon composite containing voids with a polymer comprising the reaction product of (1) furfuryl alcohol and (2) a metal complex comprising the reaction product of furfuryl amine and a metal carbonyl selected from the group consisting of tungsten carbonyl, molybdenum carbonyl and chromium carbonyl, curing said polymer and subsequently carbonizing said polymer.
