Abstract
The adsorption interaction between the filler and the binder in carbon /carbon composite was studied. The binder and the filler should be cho sen so as to realize the maximum adsorption interaction between them. The optimum composition of the composite is attained when the maximum part of the binder takes part in the adsorption layer. As a result of the interaction between the binder and the filler polar compounds, hig her molecular mass compounds and those with a condensed aromatic struc ture are concentrated in the adsorption layer. Upon thermal treatment of the composite, these substances yield a larger amount of solid resi due than the unadsorbed part of the binder.
