Fiber-Reinforced Composite Structures

High-performance fiber-reinforced composite structures are used for ballistic applications in recent years due to several advantages lightweight, high strength, and high energy absorbing capability. In this regard, it is aimed to enhance the ballistic performance of fiber-reinforced composites by hybridization method in this thesis

Two of the most used fiber types were selected as reinforcement which are E-Glass and Aramid fibers. As matrix epoxy resin was used. Homogeneous and hybrid structures were manufactured. In hybrid structures, the configuration was arranged as E-Glass layers at the front and Aramid layers at the back.

Two different hybrid composites were manufactured with 50:50 and 70:30 Aramid and E-Glass layers. The effect of the volume fraction of fabric layers on ballistic properties was investigated. Since there is a linear relationship between V50 and thickness, composite structures were manufactured with two different thicknesses, and by the equation derived V50 values for different thicknesses could be determined.

The Prepreg method is not suitable for cost-sensitive applications because compared to other methods, composite fabrics should be stored at special conditions. Refrigerators are used for storage to prevent the curing of resin at room temperature. This increases the cost of the technique with the manufacturing equipment.
