Abstract

The strength of some model binder-filler composites is investigated. Specifically, these composites consist of pitch with various fillers: anthracite, pitch coke, sand, and glass. The proportions of the components vary. The dependence of the composite’s strength on the filler/binder ratio may be satisfactorily described by mathematical models with second-order equations. The activity of the carbon and noncarbon fillers with respect to the pitch may be determined. By determining the sintering properties of the pitch, the quality of the components in the pitch composites may be determined, and the strength of the composites may be predicted.
