Due to low impact strength of C/C, it is important to evaluate impact damage properties and impact strength. In this study, the relationship between the impact load and displacement, absorbed energy of 2D-C/C specimens in a drop weight impact test are utilized for the estimation of the damage. The measured impact load is decomposed in approximation components and detail components, and is reduced higher mode of vibration by multiple resolution analysis in wavelet transform. The results are as follows: 1) It is effective for evaluating the damage zone and the initiation by using the impact load-deflection diagram and the absorbed energy. 2) The Daubechies' wavelet is useful for smoothing the impact load signals.
