EFFECT OF IRRADIATION ON COMPRESSIVE STRENGTH OF EPOXY REINFORCED WITH GLASS FIBERS

Abstract

The compressive strength was investigated for epoxy resin type (DGEBA) before and afterreinforcing with glass fibers (woven roven, chopped strand mat, and two types together as asandwich composite), with different volume fractions was prepared. The samples have beenirradiation with γ-ray with a Co60 source for (1055 hrs) with irradiation dose (0-156) KGray atroom temperature (20±2Co).The compressive strength calculated for all samples afterirradiation. The results showed that the compressive strength of epoxy samples increased afterreinforcing with glass fibers, and increased with increasing of volume fractions while thecompressive strength was decreased for all samples after irradiated with γ-ray.
