Fig. 6. Damage maps obtained from the specimens impacted at energy levels of 15 J (using an impact velocity of 2.40 m.s -1 ) and of 45 J (using an impact velocity of 4.16 m.s -1 ) employing the round-nosed steel impactor. ( The 0 o fibre direction is indicated. Results from the three replicate tests are shown. )

Some key experimental results, including maximum load, maximum displacement, duration time and damage area, may be obtained from the composites tested using the round-nosed steel (RNS) impactor and these data are compared in Table 1.
