Vakum Destekli Reçine İnfüzyon Kalıplama ile Üretilmiş Twaron®/Epoksi Lamine Kompozit Plakaların 9 mm Mermi Tehdidine Karşı Balistik Performansı Üzerine Sayısal Çalışma

Abstract

This article presents the experiments on the ballistic effect of plates formed by stacked Twaron® fabrics between 10 and 16 layer numbers impregnated with epoxy resin by vacuum infusion method and the results of Autodyn-2D® simulations using an axisymmetric model. The ballistic impact resistance of the panels produced was determined according to the NIJ-STD-0108.01 standard. All panels were tested against 9 mm FMJ bullets at an average velocity of 390 m/s with the MP5 gun for armour application. The interaction of the plates with the bullet, the post-shot damage photographs, residual velocities of the bullet were compared with Autodyn-2D® simulations. Parametric study was performed in the analysis to determine the optimum bullet velocity, layer thickness and tensile failure strain. It was observed that the data obtained from the simulations were consistent with the experiments.
