[0024] The invention provides a method for preparing a resin-based fiber reinforced composite material, including:
[0025] A) The continuous fiber is pretreated to obtain the treated continuous fiber;
[0026] Dissolve the nano-filler in a solvent and ultrasonically to obtain a nano-dispersion;
[0027] B) Connect the treated continuous fiber with an electrostatic generator, immerse it in the nano-dispersion solution, sonicate, and dry to obtain a nano-modified continuous fiber;
[0028] C) Infiltrating and curing the nano-modified continuous fiber with the resin to obtain a resin-based fiber-reinforced composite material.
[0029] The method for preparing a resin-based fiber-reinforced composite material provided by the present invention first pretreats continuous fibers to obtain treated continuous fibers.
[0030] The continuous fiber of the present invention is fiber yarn or fiber cloth; the type of continuous fiber is selected from one of glass fiber, basalt fiber, carbon fiber and...

[0055] Step 1: Put the carbon fiber cloth (TC-35, unidirectional carbon fiber cloth, 300g.m 2 ) Wash with absolute ethanol and deionized water to remove dust, oil, sizing agent and other sundries on the surface of the carbon fiber cloth; then put the cleaned carbon fiber cloth in hydrogen peroxide for 1 hour; take the carbon fiber cloth out and put it in concentrated nitric acid React for 1 hour; finally, after the carbon fiber cloth is repeatedly washed with deionized water, the carbon fiber cloth is dried at 75° C. for 8 hours, and then cooled for later use, and active groups are introduced on the surface.
[0056] Step 2: Dissolve nano-SiC with a particle size of 50nm in anhydrous ethanol with a concentration of 10%, and use ultrasound to disperse the nanoparticles in anhydrous ethanol evenly to obtain a nano-dispersion with a concentration of 10%; ultrasonic power: 100w, power density :0.5w / cm 2 , Time: 20min.
[0057] Step 3: Connect the carbon fiber cloth to the electrostatic...
