The invention provides a fiber surface treatment method, and belongs to the field of fiber surface modification. The method comprises the following steps: placing fibers in a micromolecular surfactant for surface activation, dipping the fibers in a polymer dilute solution, and drying surface moisture after ultrasonic treatment; dipping the fibers in a cross-linking agent for chemical cross-linking to form a layer of polymer cross-linked network structure on the surfaces of the fibers; and placing the fibers in a resin solution, filling the resin solution into the polymer cross-linked network structure through solution replacement, and constructing a cross-linked dual-network structure on the surface of the fibers. Compared with the prior art, the method provided by the invention has the following advantages that the tensile strength of a fiber body is improved while the bonding strength of the fiber and the resin matrix is improved, and the method is simple and beneficial to large-scale production and use.
