Embodiment 1
[0032] The effect of alkaline environment on the interfacial force of carbon fibers was studied. The carbon fiber surface is treated with NaOH solution to explore the adhesion between the carbon fiber and the resin treated in an alkaline environment, which needs to be verified by a micro-bond debonding experiment, which requires high-throughput preparation of micro-bond debonding experiments. Sample. Experimental materials: PAN-based AKSAca A-42 carbon fiber with a density of 1.78g / cm3 and a single filament diameter of 7um; EPR-L20 epoxy resin. Select 40 monofilament A-42 carbon fibers of a certain length, 20 of which are treated in NaOH solution for 15 minutes, rinse the surface of the treated carbon fiber with clean water until the surface pH is 7, and then dry it. The specific experimental steps are as follows:
[0033] The first step is to assemble the components, refer to figure 1 , 2 , 3, 4, 5, 6, the monofilament fixing fork 5 is packed into the monofilament positio...

[0037] The effect of humid environment on the interfacial force of carbon fiber surface was studied. Putting carbon fibers in an aqueous solution to explore the adhesion between carbon fibers and resins treated in a humid environment needs to be verified by microbond debonding experiments, which require high-throughput preparation of microbond debonding test samples. Experimental materials: PAN-based AKSAca A-42 carbon fiber with a density of 1.78g / cm3 and a single filament diameter of 7um; EPR-L20 epoxy resin. Select 40 monofilament A-42 carbon fibers of a certain length, 20 of which are placed in an aqueous solution for 72 hours, and then dried. The specific experimental steps are as follows:
[0038] The first step is to assemble the components, refer to figure 1 , 2 , 3, 4, 5, 6, the monofilament fixing fork 5 is packed into the monofilament positioning fork fixing device 6, and then tightened and fixed with the bolt 7; then the mold 4 is fixed on the monofilament fixing ...

[0042] The effect of different temperatures on the interfacial force on the carbon fiber surface was studied. Putting carbon fibers at different temperatures to explore the adhesion between carbon fibers and resins treated at different temperatures needs to be verified by micro-bond debonding experiments, which require high-throughput preparation of micro-bond debonding test samples. Experimental materials: PAN-based AKSAca A-42 carbon fiber with a density of 1.78g / cm3 and a single filament diameter of 7um; EPR-L20 epoxy resin. Select 40 monofilament A-42 carbon fibers of a certain length, put 10 monofilaments at a time at 100°C, 200°C, and 300°C respectively, and process for 3 hours at each temperature. After the treatment is completed, take out the single Silk. The specific experimental steps are as follows:
[0043] The first step is to assemble the components, refer to figure 1 , 2 , 3, 4, 5, 6, the monofilament fixing fork 5 is packed into the monofilament positioning...
