This research presents an experimental program for investigating rupture strength and impact resistance of precast concrete panels with different depths. Different volumes of fibers, i.e. 0%, 0.5%, 1.0% and 1.5% have been added as percentages of concrete by volume. The results show that the maximum volume of PET fiber for a desired rupture and impact resistance was 1.0%. The addition of waste PET fiber to the plain precast concrete panels has economical advantages .It tends to decrease the depth panel from (30 cm × 30 cm × 4 cm) to (30 cm × 30 cm × 3 cm) and the percentage of increase of rupture strength was 34.27% and the percentage of increase of impact resistance was 157.14% for reinforced concrete panels (30 cm × 30 cm × 3 cm) aged at 90-days compared with plain panels of (30 cm × 30 cm × 4 cm). In the impact test the visual observation is that the specimens of fiber reinforced precast concrete panel (FRPCP) have remained together in one piece though broken whilst plain concrete specimens have exhibited the total disintegration.
