INVESTIGATION ON RESIDUAL VELOCITIES OF LAMINATED COMPOSITE TARGETS SUBJECTED TO BALLISTIC IMPACT

The strain rate effects of Twaron fiber material, quasi static and ballistic impact penetration of laminated composite targets made of Twaron fabric and phenolic resin are investigated by means of MTS (material esting system), split Hopkinson tension bars and ballistic impact apparatus. The tensile impact experiments on Twaron fiber material are performed at strain rate 0.01/s, 180/s, 480/s and 1000/s. Experimental results show that the mechanical properties of Twaron fiber material are little rate dependent. A simple model to predicted residual velocity of laminated composite targets subjected to ballistic impact is proposed on the basis of experimental data of quasi static penetration through the targets. The predicted residual velocities show good agreement with the experimental residual velocity.
