Ballistic investigation of polymer bonded borided steel sheets [2]

Abstract

In this study, it was aimed to produce composite laminates of boronized AISI-1010 steel plates as an alternative protection against the threat level BR-2 defined in the EN-1063 standard. Cold rolled AISI-1010 steel plates were cut into hexagonal plates with 45 mm diagonals. These hexagonal plates were boronized by pack boronizing method at 950?C for 3h. The characterization of the boronized samples was carried out by SEM-EDS, XRD, and Vickers microhardness measurement. Composite laminates having two different thicknesses were produced by bonding boronized AISI-1010 steel plates with a binary component acrylic adhesive and pressing. Armor plates were produced by combining hexagonal composite laminates together on a thin kevlar sheet to provide the necessary integrity. The ballistic tests of these plates were performed for the threat level BR-2 defined in the EN-1063 standard. © 2017 Elsevier B.V., All rights reserved.
