Investigation of the usability of laminated hybrid composites as a body armor material

In this thesis, usability of laminated hybrid composites as a body armor material has been investigated experimentally. As part of the study, ballistic tests of glass/aramid/carbon fiber laminated composite plates with different reinforcing angles, in different numbers and thicknesses have been carried out and the results are analyzed. To this end, 4 plates, each having different thicknesses and comprising 30 laminates in 200 mm x 200 mm size are produced by hand lay-up method. 0°, 45°, plain and twill fabrics have been used to analyze ballistic performances of different fiber reinforcing angles. Ballistic tests of the laminated hybrid composite plates that are produced are carried out in Elazığ Special Operation Branch Office, using a Beretta gun loaded with 9mm FMJ bullets. Experiments made with an balistical test equipment that prepared in accordance with (NIJ 0101-06) international standards. During balistic experiments, velocity and sag values of bullets measured and evaluated.
