| Abstract | ||
| Epoxy-phenol system were prepared and studied before and after reinforcing with glass fibers (woven roven 0ο-90ο direction) with volume fraction (vf = 48%). The samples irradiated with uv radiation with wave length (λ= 320 nm), irradiation energy (1.5 watt/ cm2) for 50 hours. The dielectric constant and thermal conductivity measured for all samples before and after irradiation with uv radiation. The results showed that the increasing percentage of phenolic resin in the blends decreasing the dielectric constant and thermal conductivity of all samples before and after irradiation with uv radiation. While the results before irradiation showed the effect of glass fibers in increasing the dielectric constant and thermal conductivity. Finally the results showed that the dielectric constant decreased, thermal conductivity increased for all samples after irradiation with uv radiation. | ||
