Cam ve basalt fiber kompozitlerde çelik fiberin mekanik özellikler üzerindeki etkisi

Steel fiber is the most common metal fiber used due to its cost-effectiveness, high performance, and availability despite its heavy weight. This study investigated the results of combining steel fiber with glass or basalt fiber. Epoxy and polyurethane were used as matrix materials and 58 composite laminates were created. The study is divided into two parts. In the first part, composite laminates were created of glass fiber, basalt, and the three mesh sizes (200, 100, and 50) of steel fibers reinforced epoxy. In the second part, similarly, 29 hybrid and non-hybrid composite materials were created, but instead of epoxy, polyurethane was used. In general, this part aims to investigate the influence of switching the matrix on the characterization of hybrid composite materials. The mechanical properties of prepared composite specimens were characterized, and scanning electron microscope observation was performed around the fracture region of the tested specimens. The results revealed that the replacement of some basalt and glass layers with steel layers leads to a positive hybridization effect of the overall produced hybrid composites. Consequently, the potential to hybridize steel fiber with glass fiber and basalt fiber could create new materials with unique physical structures and synergistic effects on mechanical properties. The steel/glass and steel/basalt fibers hybrid composites exhibit promise in structural applications because of their good tensile strength, flexural strength, strain, and energy absorption compared to non-hybrid composite laminates.
