[0023] DETAILED DESCRIPTION OF THE INVENTION A fiber surface treatment method is described in this embodiment, the method comprising the steps of:
[0024] Step 1: The fiber is immersed in 0.1% to 15% small molecular surfactant solution 1 to 120 min, and the small molecule surface activator can form a chemical link to the fiber inert surface, improve the surface of the fiber surface, and activate fiber 1;
[0025] Step 2: Immersion of the activated fiber 1 in a concentration of 1% to 40% polymer solution 1 min ~ 60min, ultrasonic treatment, after drying, the surface is dried to activate the fiber 2;
[0026] Step 3: Immerse the activation fibers 2 in a 0.1% to 60% crosslinker solution, chemically crosslinking, the polymer forms a three-dimensional crosslinked network structure on the surface of the fiber to obtain activated fibers 3;
[0027] Step 4: Immersion the activated fiber 3 in a 0.1% -15% resin solution 1min to 60 min, and fill the resin solution to the polymer cross-linking

[0030] DETAILED DESCRIPTION OF THE INVENTION 2: DETAILED DESCRIPTION OF THE INVENTION A Fiber Surface Treatment Method of FIG. 1, in step one, the fiber is PBO fiber, aramid fiber, carbon fiber, polyester fiber, glass fiber, nylon 66, polyphenylene sulfide One of the fibers, basalt fibers or ultra-high molecular weight polyethylene fibers.
Example Embodiment
[0031] DETAILED DESCRIPTION OF THE INVENTION 3: DETAILED DESCRIPTION OF THE INVENTION A fiber surface treatment method, in step one, the small molecule surface activator is a silane coupling agent, ethylene chloride, adipic chloride, butylene diacyl chloride, C One or more mixed in diachlor chloride, glutaraldehyde or caprolactone. These small molecular surface activators are capable of activating the fiber surface, increasing the fiber surface active group, facilitating the composite of the fibers and the polymer network.
[0032] DETAILED DESCRIPTION OF THE INVENTION 4: DETAILED DESCRIPTION OF THE INVENTION A fiber surface treatment method according to the third embodiment, the silane coupling agent is KH-550, KH-560, KH-570, KH-151, KH-171 or KH-792. One or more compounds. These silane coupling agents can form an amine group on the surface of the fibers to increase the surface energy of the fibers.
