EXPERIMENTAL INVESTIGATION OF THE MECHANICAL CHARACTERISTICS OF PHOTOLUMINESCENT COMPOSITE MATERIALS

Crystal 85-5 epoxy resin modified with MHG-4E photoluminescent powder (average particle size 5–15  \(\mu\) m) and FV-530D photoluminescent powders (average particle size 25  \(\mu\) m) photoluminescent powders were studied by mechanical uniaxial tension and three-point bending tests. The dependence of the elastic modulus on filler concentration was obtained. The photoluminescent properties of the resulting composites were examined. The dependence of the afterglow intensity on filler content in the composite was determined.
