INFLUENCE OF HEAT TREATMENT ON THE FORMATION OF EPOXY COMPOSITE MATERIALS FOR BALLISTIC PROTECTION

Abstract

The resistance of epoxy composite materials containing glass fabric to static and dynamic loads was investigated. The
optimal heat treatment regime for epoxy fiberglass materials was determined. This ensures high adhesion strength of the
polymer matrix to the filler. It also provides high impact toughness and strength for the composites. The nature of the
destruction of the epoxy fiberglass materials containing aramid fabric and glass fabric under the influence of dynamic loading
of a calibrated size impactor was investigated. The influence of the nature of the filler and the density of the glass fabric on the
resistance to brittle fracture of the fiberglass materials under the optimal heat treatment regime was determined. The developed
epoxy composite materials with increased resistance to dynamic loads are expedient to use for the manufacture of elements of
individual ballistic protection.
