Recently, hybrid nanofillers loading has been utilized to fabricate multifunctional composites. In this study, silica (SiO₂) and cobalt ferrite (CoFe₂O₄) nanoparticles were combined to form a new hybrid composite structure. Nanofilled glass/epoxy hybrid composite laminates were fabricated using hand lay‐up technique. SiO₂/CoFe₂O₄ hybrid fillers were dispersed in epoxy matrix with sonication. The effect of incorporating SiO₂/CoFe₂O₄ hybrid nanoparticles on the mechanical properties of glass fiber/epoxy composites was investigated. The resultant SiO₂/CoFe₂O₄ hybrid nanocomposites showed good mechanical properties as compared to hybrid nanocomposites fabricated by individually loading SiO₂ or CoFe₂O₄ nanoparticles as well as pristine glass fiber/epoxy composite. A visible improvement in the mechanical properties was observed with hybrid nanocomposite that consisted of CoFe₂O₄/epoxy core layers and SiO₂/epoxy skin layers detached with intermediate layers of hybrid SiO₂ + CoFe₂O₄/epoxy. Scanning electron microscopic (SEM) images of tensile and flexural fractured surfaces reveal a good fiber/matrix interfacial bonding.
