In this paper. the estimation of dynamic interlaminar fracture toughness on fracture mode 0 in CFRP(carbon fiber reinforced plastics) laminates is made. Dynamic ENF(End Notched Flexure) apparatus used in this paper is manufactured by using Split Hopkinson Pressure Bar. The static and impact load history in the CFRP specimen is measured by using manufactured dynamic ENF tester and 3-point bending test is carried out to find the load history. Also. dynamic interlaminar fracture toughness can be found by using the j integral obtained from dynamic analysis in consideration of inertia-force effect.
