 It was observed that the delamination failure is more dominant than the fiber and matrix damages under low velocity impact. Further, the delamination area on the top layer was minimum due to the compressive stress. The total delamination area in the QI laminates was higher than the cross-ply laminates.  The energy absorbed by the QI laminate is 5.2% higher than that of the cross-ply at 65 J. At 41.6 J impact energy, the results showed that the energy absorption of QI laminate is 9.1% greater than cross-ply laminate. This is due to the improved impact resistance of the CFRP laminates by adding +45 o /-45 o laminae which has substantial contribution in reducing the shear stress under impact. Whereas in low impact energy levels (2.6 J and 10.4 J)), the cross-ply laminates exhibit more energy absorption than the QI laminates.  It was also noted that, the fiber damage on QI laminate was less compared to the cross-ply laminate at all energy levels. 6.
