. The compressive response of a 3D carbon-carbon composite under shock wave was studied in a plateimpact configuration. Two directions of in~pact were achieved until a nominal value of longitudinal stress of 2.5 GPa. The measured wave profiles are consistent with previous results on 3D composites and confirm the behavim of such materials under impact. It is shown that the initial loading is decomposed in two waves. The first one is transmitted by the longil~rdinal fibres, the second one correspouds to the propagation of a shock wave in the 'matrix'. Macroscopic characteristics of this nlaterial arc provided.RCsumC . On presente la reporise sous choc d'un conlposite 3DCC i partir d'essai d'impact de plaques. Deux directions d'anisotropie ont tte etudiis jusqu'h une contrainte maximum de 2.5 GPa. La rorrne des diagrammes de vitesse est coherente avec les resultats deja obtenus sur les conlposites 3D et confirme leur co~nportement sous choc. On montre que la sollicitatio~~ initiale se decompose en deus ondes. La prernitre est transport& par les fibres longitudinales, la seconde par la matrice. On presente des caracteristiques macroscopiques calculks sur ce composite 3DCC.
