Abstract

The incorporation of nanoparticles into composites has attracted significant attention from researchers due to their ability to enhance mechanical and physical properties without adding excessive weight. Nanoceramics, a type of nanoparticle, possess unique geometric and chemical characteristics and have widespread applications across various industries. In this study, the researchers investigated the influence of nanoceramics on the mechanical behavior of hybrid epoxy/glass fiber composites under ballistic loading conditions. The hybrid samples were fabricated using an innovative vacuum-assisted resin transfer molding technique (VARTM) and were subjected to tension and flexure tests. The results demonstrated that the hybrid samples exhibited improved mechanical properties compared to the control sample. Among the samples, the 3% nanoceramics sample demonstrated the most favorable performance, exhibiting increased elastic modulus, ultimate tensile strength, and flexural strength compared to the pure sample. Ballistic impact tests revealed that the ballistic efficiency initially decreased with increasing nanoceramics content but eventually increased when the concentration reached 7%. The ballistic limit velocities and the absorbed energy by the target varied depending on the nanoceramics content. These findings highlight the strain rate sensitivity of glass fibers and the potential of nanoceramics to enhance the ballistic properties of composites.
