ResumoComposite armor panels with boron carbide ceramic as striking face, backed with carbon nanotube-ultra high molecular weight polyethylene (CNT-UHMWPE), have been fabricated as lightweight body armors. The armor panels were tested against actual ammunitions through self-loading rifle (SLR) and AK-47. Slip lines were observed in boron carbide with high energy bullets. CNT-UHMWPE composite backing resulted in a low back face signature (BFS) due to the formation of a strong bond between CNT and UHMWPE and high energy dissipation through this composite. The role of CNT in the ballistic protection of this composite armor has been explained with the help of necessary characterization by electron microscopy, X-ray radiography, Fourier transformed infrared spectroscopy and differential scanning calorimetry.
