The mechanical behavior of the nanomodified hybrid epoxy matrix was investigated in glass fiber reinforced plastics (GFRP). In this study, five nanocomposites enriched with as received halloysite, nanomer I.28E, HNT-APTES, and the hybrid combinations of the two HNTs with the nanomer I.28E were successfully fabricated. To evaluate the effects and morphological characteristics of the individual fillers and the hybrid configurations on the epoxy resin matrix, TGA, DSC, and DMA were analyzed. To understand the effect of the five configurations on the neat GFRP laminate, mode I interlaminar fracture toughness, tensile, and vibration properties were investigated. Electron microscopy testing techniques were used to support the results and conclusions. The addition of the filler material showed significant improvement in the GFRP materials’ properties, with the hybrid configuration showing exceptional results. Overall, the work demonstrated the ability to tailor GFRP composite properties using hybrid modified fillers. The data suggest that toughening epoxy with nanomodified filler materials is instrumental to various applications by improving and maintaining the overall integrity of structures, such as in the automotive and aerospace industries.
