In this study, unsaturated polyester resin for general use and woven E-glass fiber were used as the components required for structure formation and as the reinforcement material. In the production of target composite plates prepared as square and circular sections, the thickness of the composite plates was variable, together with the number of fiber layers. The shots were fired on target composite plates from a distance of 10 m at the range, using two different weapons that fired 22-caliber and 9-mm rounds, respectively. As a result of the shots, it was determined that if the number of woven fiber layers was 9 and the plate thickness was greater than 12 mm, the target composite was successful against 22 caliber and 9 mm bullets. The level of protection for composite plates has been determined to be IIA according to NIJ Standard-0101.06. The target is of vital importance in shooting with a gun, and in this study, the characteristics of the target composite plate that prevent the bullet from passing gave results according to the determined production operating parameters. For increased shell calibers, it is necessary to carefully plan the target composite production parameters and necessarily conduct field shooting experiments.

Bu çalışmada, matris yapı malzemesi olarak genel kullanım amaçlı doymamış polyester reçine ile yapı oluşumu için gerekli bileşenler ve takviye malzemesi olarak dokuma E-cam elyaf kullanılmıştır. Kare ve daire kesitli olarak hazırlanan hedef kompozit plakaların üretiminde, elyaf tabaka sayısıyla birlikte kompozit plakaların kalınlıkları değişken olarak kullanılmıştır. Hedef kompozit plakalara, poligonda 10 m mesafeden, sırasıyla 22 kalibre ve 9 mm mermi atan iki farklı silah kullanarak atışlar yapılmıştır. Atışlar sonucunda, dokuma elyaf tabaka sayısının 9, plaka kalınlığının 12 mm’den daha fazla olması halinde, 9 mm mermi'ye karşı hedef kompozitin başarılı olduğu belirlenmiştir. Kompozit plakalar için koruma seviyesinin NIJ Standard-0101.06’ya göre IIA olduğu belirlenmiştir. Silahla atışlarda hedef hayati önem taşımaktadır ve bu çalışmada, merminin geçmesine engel olan hedef kompozit plaka özellikleri, belirlenen üretim çalışma parametrelerine göre sonuçlar vermiştir. Artan mermi kalibreleri için hedef kompozit üretim parametrelerinin dikkatli bir şekilde planlanması ve mutlaka saha atış deneylerinin yapılması gerekir.
