[0160] The only difference from Example 3 is that no carbon fiber is added to the carbon fiber hybrid liquid.

[0161] Experimental example 2.

[0162] The only difference from Example 3 is that cerium oxide is not added to the carbon fiber hybrid liquid.

[0163] Experimental Example 3.

[0164] The only difference from Example 3 is that nano zirconium oxide is not added to the carbon fiber hybrid liquid.

[0165] Experimental Example 4.

[0166] The only difference from Example 3 is that stearic acid is not added to the carbon fiber hybrid solution and the sodium dodecylbenzene sulfonate solution is replaced by water.

[0167] Taking the product under acid resistance, solvent resistance and high temperature resistance as an example, the performance test is carried out, and its performance is tested as follows;

[0168]

[0169] It can be seen from Experimental Examples 1-4 that carbon fiber is not added to the carbon fiber hybrid liquid, and the performance of the product changes. Among the components of the carbon fiber hybrid liquid, the performance deterioration is the most obvious, followed by the absence of nano zirconium oxide. At the same time, cerium oxide is not added to the carbon fiber hybrid liquid, stearic acid is not added to the carbon fiber hybrid liquid, and the sodium dodecylbenzene sulfonate solution is replaced by water. The performance of the product has a trend of deterioration to varying degrees. The carbon fiber hybrid liquid composed by the specific method of the present invention has the most significant performance effect of the product. At the same time, the composition of the carbon fiber hybrid liquid is proprietary, and the technical effect of the present invention cannot be achieved by replacing it with other methods.

[0170] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0171] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
