Abstract The primary challenges in utilizing thermoplastic poly(ether‐ether‐ketone) (PEEK) stem from its inherent lack of toughness production settings. Traditional methods enhancing often compromise other essential properties the material. This research focuses on optimizing PEEK resin composites by integrating graphene oxide (GO) and silicone rubber (SR) particles into matrix to formulate multiphase composites. A detailed investigation was carried out assess impact these two distinct properties. In evaluation across various composite materials, a notable enhancement evident GO/PEEK, SR/PEEK, GO/SR/PEEK ternary compared pristine PEEK. Furthermore, maintained comparable stiffness thermal resistance standard Tensile strength, fracture absorbed energy, versus pure indicated increases 18.38%, 174.53%, 46.37%, respectively. Fracture analysis demonstrated that multi‐particle modification significantly complicated toughening mechanisms, including voiding, shear band formation, crack deflection, plastic deformation. findings this study propose viable material design principle for engineering materials effectively balance strength toughness. Highlights with between GO SR exert synergistic effect mechanical deformation is promoted as main mechanism. enhanced crystallization, improving
