Embodiment 1
[0038] (1) First use the surface of the glass fiber cloth, and add the high temperature resistant coupling agent with a mass ratio of 1.5% to the solvent in N, N-dimethylacetamide (DMAc) solvent, at room temperature and at a speed of 300rpm Mix for 10 minutes to obtain a surface treatment solution for glass fiber cloth.
[0039] (2) Soak the glass fiber cloth in the surface treatment solution prepared in step (1) for 5 minutes; take it out and dry it naturally for 30 minutes, then dry it in a normal pressure oven at 50°C for 10 minutes, and then dry it at 100°C for 10 minutes , Dry at 160°C for 30 minutes to obtain a surface-treated glass fiber cloth.
[0040] (3) Dissolve 30 parts of PPESK resin in 100 parts of a mixed solvent with DMAc: DMF: chlorobenzene = 1: 1: 1 (volume ratio), stir at room temperature for 30 minutes, the solution is homogeneous, and a prepreg is prepared.
[0041] (4) Pour the prepreg prepared in step (3) into the dipping tank, immerse the glass fiber c...

Embodiment 3
[0052] (1) First use the surface of the glass fiber cloth, and add the high temperature resistant coupling agent with a mass ratio of 1.5% to the solvent in N, N-dimethylacetamide (DMAc) solvent, at room temperature and at a speed of 300rpm Mix for 10 minutes to obtain a surface treatment solution for glass fiber cloth.
[0053] (2) Soak the glass fiber cloth in the surface treatment solution prepared in step (1) for 5 minutes; take it out and dry it naturally for 30 minutes, then dry it in a normal pressure oven at 50°C for 10 minutes, and then dry it at 100°C for 10 minutes , Dry at 160°C for 30 minutes to obtain a surface-treated glass fiber cloth.
[0054] (3) Use PPENK / PPESK blended resin as raw material, and its ratio is: PPENK / PPESK=8:2. Dissolve 30 parts of the blended resin in 100 parts of a mixed solvent of DMAc:DMF:toluene=1.2:1:1 (volume ratio), and stir at room temperature for 30 minutes to obtain a uniform solution to obtain a pre-preg.
[0055] (4) Pour the pr...
