Despite the numerous benefits of thermoset epoxy resin, such as its high thermal and chemical stability and excellent adhesion, its use is limited due to its fragile and rigid structure, low crack initiation, and potential loss of integrity from damage. To address these limitations, various types of fillers, such as fiber, particle, and crystal filaments, have been incorporated into the epoxy matrix. The focus of this study is on the synthesis of CaTiO3-Ca2SiO4 nanoparticles through the sol-gel method and their incorporation into the epoxy matrix using the ultrasonic method, along with polyvinyl acetate (PVAc) and carbon fiber (CF). These ingredients’ impact on the epoxy resin’s mechanical behavior and the optimum weight percentages were evaluated using response surface methodology-central composite design (RSM/CCD). The combination of nanoparticles and carbon fibers had a synergistic effect on the overall stress of the epoxy resin, resulting in a significant increase (236.7% and 188.9%, respectively) compared to pure epoxy and epoxy with PVAc.
