A multi-scale synergistic modification technology is proposed to strengthen and toughen epoxy resin matrix composites, which can be used in the direct extrusion fabrication process. The toughness performance of epoxy resin matrix composites can be improved without compromising other advantages by adding micrometer- and nanometer-scale fillers to the matrix and optimizing the content of fillers, surface treatment process, dispersion method, and other parameters. We analyzed and discussed the mechanical properties of epoxy-based composites with micrometer-scale fillers, nanometer-scale fillers, and mixed multi-scale fillers. When 15 phr carbon fibers (15CFs), 6 phr rubber nanoparticles (6RNPs), and 1 phr carbon nanotubes (1CNTs) are added to epoxy resins (EPs), the tensile strength reached 91.6 MPa, 28.8% higher than that of the pure EPs; the achieved elastic modulus 4.72 GPa, 77.4% higher than the pure EPs; the fracture toughness was 2.97 MPa m<SUP>1/2</SUP>, 241.4% of the pure EPs, while the impact strength reached 63.4 kJ/m<SUP>2</SUP>, 369.6% higher than the pure EPs. The results show that the multi-scale reinforcements exhibit a synergistic effect on the strength and toughness of the composites.
