Behind armour blunt trauma(BABT)is a body injury resulting from the deformation of the back surface of armour as a result of a bullet *** the case of textile body armour,the severity of the injury may depend on the material of the fibres,but also on the geometric structure of the *** article focuses on experimental research into injuries of the human body protected by ballistic packets made of biaxial and triaxial fabrics,during a non-penetrating impact from a Parabellum 9 mm×19 mm Full Metal Jacket(FMJ)bullet,at a speed of 406±5 m/*** experimental research,the fabrics had a comparable surface weight and were made of the same Kevlar^(■)29 *** ballistic packages were made of 30 *** part of the work,a physical model of the human body was *** human body model consisted of a model of the heart,lungs,and skeletal and muscular *** the bullet impact,the pressure forces were recorded using sensors located at selected points of the human *** bullets hit five selected places on the body that were considered critical,from the point of view of maintaining a human’s vital *** was found that,during firing,pressure increases both at the site of impact and in the internal organs,which can lead to multi-organ *** a result of the experimental analysis,it has been shown that the pressures exerted on specific organs are always lower in the case of body protection with a ballistic packet made of triaxial fabrics,compared to a packet made of biaxial fabrics.
