1100 mm. Tab. 8 shows the crack patterns for the strengthened models with 0.45 mm thickness of CFRP layer under 6.3 m/s impact velocity for both types of beams reinforced with Ph 12 and CFRP bars, with different values of impactor positions. Fig. 15 plots the displacement- time (D-t) histories to compare the displacement at midspan of the beam for variable impactor position.
