Experimental investigation of the mechanical characteristics of photoluminescent composite materials

Uniaxial tension and three-point bending tests were performed for polymer composite samples made of Crystal 85-5 epoxy resin modified with MHG-4E (average particle size 5–15 $\mu$m) and FV-530D (average particle size 25 $\mu$m) photoluminescent powders. The dependence of the elastic modulus on the filler concentration was obtained. The photoluminescent properties of the resulting composites were studied. The dependence of the has been established afterglow intensity on the filler content in the composite was determined.
