The work investigated the influence of the nature of the binder and filler modifier on the rheological properties of epoxy composites based on ED-20 resin. The binder was modified by introducing epoxidized soybean oil and a mixture of polyvinyl butyral with epoxidized soybean oil. Copper polyvinyl chloride, and aluminum oxide, as well as their mixture, were used as fillers. It was found that filling and modification of the matrix change the nature of the flow curves. The resulting composites are characterized by a uniform distribution of the filler.
