The research is concerned with the bonding and pyrolysis characteristics of two synthetic binders. The binders, alumina-condensed furfuryl alcohol resin and acenaphthylene pitch, were evaluated both by themselves and in conjunction with selected fillers to determine binder-filler interactions during pyrolysis and to develop a more complete understanding of the carbon bonding process. The data accumulated from a number of techniques are presented and interpreted. Pyrolysis and physical property data for specimens molded with both the resin and pitch binders are also presented. It has been found that some fillers are essentially unbondable by carbon, while others can materially alter binder pyrolysis. Author
