Abstract
In the optimization of the ballistic vest to prevent atrocity and stabbing, two fabrics were utilized: a ballistic plate made of synthetic fiber Endumax® Shield XF 33 and Twaron® SRM 509. Test the thickness and weight of the fabric before being tested for atrocity and stabbing protection. Finally, test the ammunition protection. The results were as follows: (1) The thickness of Twaron® and Endumax® fabrics. The average was 0.44300 and 0.22000 mm., and the standard deviation and variance were low. (2) The weight of Twaron® and Endumax® fabrics. The average was 1.99300 and 1.45100 g., and the standard deviation and variance were low. (3) Protective atrocity P1/B at the L2, E1 level, the average energy is 33.176 joules. The average blade depth is 0 mm., within the specified standard. Protective atrocity P1/B at the L2 and E2 levels has an energy average of 50.52 joules. The average blade depth is 1 mm., which is also within the specified standard criteria. (4) Protective stabbing SP/B at the L2 and E1 levels, the energy average is 33.54 joules. The average blade depth is 0 mm., within the specified standard. Protective stabbing SP/B at the L2 and E2 levels, the average energy is 49.894 joules. The average blade depth is 7.6 mm., which is also within the specified standard criteria. (5) Ballistic vest plate test with 0.44 MAG SJHP ammunition 240 g. The average bullet velocity was 437.78 m/s. The collapse footprint is 19.6 mm., within the specified standard. Tested with 9 mm. FMJ ammunition 124 g. The average bullet velocity was 438.15 m/s. The collapse footprint is 18 mm., which is also within the specified standard criteria. From various test results, it can be concluded that the ballistic vest provides excellent protection according to military standards and is suitable for security officials' work.
