Abstract

The composition of an epoxy composition modified with polyarylsulfone PSFF-30 was proposed and the physicochemical and rheological properties of the resulting melt binder were studied. Based on an epoxy-polysulfone binder, glass and carbon fiber plastic samples were made using the vacuum furnace molding method, and the strength and thermophysical characteristics of the polymers were assessed. It has been established that this modification of the epoxy- polysulfone binder reduces the volume fraction of pores in fiberglass with woven filler T-10-14 by 2,7 times, and in carbon fiber with filler VTkU-2.200 – 2 times.
