FORMATION OF EPOXY COMPOSITES BASED ON RECYCLED FILLERS OF SYNTHETIC ORIGIN

Abstract

A method of processing glass-fiber polymer composite materials by mechanical grinding with subsequent classification of particles and formation of epoxy composite samples is presented. An increase in the physical and mechanical characteristics of epoxy composite materials based on secondary raw materials, structured at a final temperature of 170°C, is determined. A decrease in the compressive strength and gel fraction content of the epoxy composite material as a result of introducing a filler into the composition in an amount of more than 200 wt. parts is established. However, the use of a filler in an amount of 600 wt. parts provides an increase in the impact strength of epoxy composites. The using of smaller particles of secondary raw materials improves processability of the composition and increases the compressive strength of epoxy composites.
