Özet

In this study, Kevlar/epoxy composite materials with 6.5 mm thickness were subjected to high velocity impact tests which are conducted from 456 m/s to 801 m/s using single-stage gas gun system experimentally, because the resistance of composite materials to high-velocity impacts depends on the thickness and type of fibers used in many applications such as defensive and aerospace structures in the aerospace sector. The case of military applications, shocks such as shells and missiles have a high-velocity impact. Composite materials were manufactured by vacuum assisted resin infusion moulding (VARIM) method. Waterjet cutting machine was used to prepare the samples with 100 mm x 100 mm. The result shows that, residual velocity increases by increasing impact velocity. However, percent reduction in velocity decreases by increasing impact velocity
