Effect of irradiation on compressive strength of epoxy reinforcedwith glass fibers

الملخص EN

The compressive strength was investigated for epoxy resin type (DGEBA) before and after reinforcing with glass fibers (woven raven, chopped strand mat, and two types together as a sandwich composite), with different volume fractions was prepared.

The samples have been irradiation with γ-ray with a Co60 source for (1055 hrs) with irradiation dose (0-156) Gray at room temperature (20 ± 2Co).

The compressive strength calculated for all samples after irradiation.

The results showed that the compressive strength of epoxy samples increased after reinforcing with glass fibers, and increased with increasing of volume fractions while the compressive strength was decreased for all samples after irradiated with γ-ray.
