Development of knife- and bullet-impact-resistant composite structures

  • Published:
Mechanics of Composite Materials Aims and scope

Two types of layered composite structures — based on an aramid fabric covered with alumina microparticles and on polycarbonate — have been considered. Experimental investigation of the mechanical properties and puncture resistance of the first material was carried out. The results of quasi-static, dynamic, and firearm tests of the composite plates are presented. The minimum distance from a first puncture where the stubbing protection is safe was found by using the digital image correlation method. A FEM analysis of bending and tension of composite plates with a defect of complex geometry was performed. The analytical results obtained are compared with test data.
