In this paper, we performed the experimental study of Taylor test of cylindrical polycarbonate material, a flat ended cylindrical polycarbonate ballistic with 22 mm diameter and 64 mm long was impacted on the rigid target at speeds ranging from 118 m/s to 278 m/s. High-speed photography was used to monitor the progression of deformation within the sample, and impact pressure was measured by polyvinylidene fluoride (PVDF) membrane, photoplastic method was used to analysis deformation characteristic after impact. The results show that deformation process of polycarbonate Taylor impact is in agreement with Jones's two-stage model at low-speed impact and three two-stage model at high speed impact, impact shock pressure oscillation decays on impacting flat ended, and impacting flat ended has been destroyed when impact speed is 278 m/s. Deformation model transition region in the samples internal strain was found.
