Study of new composite materials based on epoxy resin with photoluminescence effect

Strontium aluminate doped with europium with various particle sizes was added to epoxy resins ED-20 and Crystal 85-5 in a mass concentration from 0% to 17%. Mechanical tests for three-point bending and instrumental indentation were carried out. The relationship between modulus of elasticity and hardness and concentration of the filler were obtained. The photoluminescent properties of the resulting composites have been studied. The relationship between luminescence intensity and decay time and the content of composite components were established.
