Embodiment 1
[0022] like figure 2 As shown, select 10 parts of industrial phenolic resin, add 89 parts of industrial alcohol as a solvent, add 5 parts of triethanolamine as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak this as a The binder is then purged with 100Kpa compressed air to remove excess binder; placed at room temperature at about 25°C for 4 hours, then moved into an oven with a temperature of 120°C, and the fiber bundles are cured for 5 hours.
Embodiment 2
[0024] Select 15 parts of industrial phenolic resin, add 78 parts of industrial alcohol as a solvent, add 7 parts of triethanolamine as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak this as a binder , and then use 100Kpa compressed air to purge to remove excess binder; at room temperature about 25°C, place for 5h, then move into an oven with a temperature of 130°C, and cure the fiber bundles for 4h.
Embodiment 3
[0026] Select 20 parts of industrial phenolic resin, add 75 parts of industrial alcohol as a solvent, add 8 parts of triethanolamine as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak this as a binder , and then use 100Kpa compressed air to purge to remove excess binder; place at room temperature about 25°C for 5h, then move it into an oven with a temperature of 140°C, and cure the fiber bundles for 3h.
