Preliminary Study on Multilayer Bulletproof Concrete Panel: Impact Energy Absorption and Failure Pattern of Fibre Reinforced Concrete, Para-Rubber and Styrofoam Sheets

This manuscript presents the preliminary test results from the multilayer bulletproof concrete panel project. The purposed multilayer panel consisted of steel fibre reinforced concrete, Para-rubber and Styrofoam sheet. In this study, the failure patterns and energy absorption of each material with different thickness subjected to direct fire arm with 9 and 11 mm. bullets were investigated. The obtained information will later be used in designing the multilayer bulletproof concrete panel based on combination of energy absorption. The results showed that the energy absorption of each material increased with the increasing thickness. In case of FRC, the energy absorption also depended on fibre type and volume fractions. Comparing at the same thickness, FRC was the most effective energy absorption followed by Para-rubber and Styrofoam sheet.
