Abstract
AbstractRecently, 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/CoFe2O4hybrid fillers were dispersed in epoxy matrix with sonication. The effect of incorporating SiO2/CoFe2O4hybrid nanoparticles on the mechanical properties of glass fiber/epoxy composites was investigated. The resultant SiO2/CoFe2O4hybrid nanocomposites showed good mechanical properties as compared to hybrid nanocomposites fabricated by individually loading SiO2or CoFe2O4nanoparticles 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.
