Abstract

Nowadays ballistic protective helmets are made of synthetic composites like para-aramide fibers and advanced laminate materials (UHMWPE). The absorption of impact energy occurs through plastic and elastic deformation. The so-called 'dynamic back face deflections' caused by the kinetic energy of the projectile during the ballistic impact can generate serious, irreversible traumatic head injuries. That leads to the question: Which cranio-cerebral injuries are to be expected due to a bullet impact without penetration and which clinical implications for the wearer of the helmet can arise? This paper presents a first prototype of a head-shaped measurement setup for ballistic impact tests of combat helmets. Shooting tests were conducted and force-time sequences caused by the helmet-head contacts during the impact were obtained. The force values of additional trials are planned to be loaded onto a 3D human head finite element model. The objective of the work is the biomechanical interpretation of the simulations. They shall allow conclusions on possible cranio-cerebral injuries and clinical implications.
