The effect of glass fibers on the protective and mechanical properties of Xrayshielding polymer composites

Various research has been done in manufacturing and designing different types of radiationshielding. In this study, lead-free polymer composite panels with new special formulations have beenprepared and characterized to prevent radiation leakage in medical facilities at the diagnostic energyrange (۶۰ – ۱۲۰ keV). Epoxy resin is used as a binder along with large amounts of mineral highdensityfiller. SEM micrographs showed a homogeneous distribution of filler particles. Then theeffects of adding glass fiber on the mechanical and shielding properties of composite panels wereinvestigated. Samples containing ۰.۵ % by weight of glass fiber showed higher bending and tensilestrengths than samples without fiber. However, samples without fiber have higher density andattenuation coefficient.
