Abstract

In this work, wire mesh metallic fibers and the nanomaterial titanium oxide TiO₂ were used to reinforce the epoxy matrix to create the hybrid composite material specimens by the hand lay-up method. The effects of adding specific fractions of TiO₂ nano material on the dynamic characteristics of wire mesh hybrid composites were investigated. The vibrational characteristics (natural frequency and damping ratio) and mechanical characteristics (tensile and bending stresses) were examined. The numerical analysis for Bending and vibration cases was performed using ANSYS ABDL 2017 R2. Experimental results showed that the addition of TiO₂ nanoparticles significantly improved tensile strength and flexural strength in epoxy-steel wire-TiO₂ composites. However, increasing the nanoparticle ratio to the maximum values led to reduced performance. The composites showed a balance between stiffness and strength when optimized at 5 wt% TiO₂ and moderate layer counts. Natural frequencies and damping characteristics were affected by fiber volume, layering, and nanoparticle content
