[0018] The preparation method of half-layer thermosetting resin matrix composite structure, see appendix figure 1 ,Specific steps are as follows:
[0019] a. First, use a single-layer fabric as a reinforcement, adopt the method of compounding one side of the single-layer fabric with a thermoplastic resin, and through process control, form a thermoplastic resin prepreg 1 in a part of the thickness of the single-layer fabric. Single-layer The material of the fabric is glass fiber or carbon fiber, the structure is one or more of plain weave, twill weave or satin weave, and the thermoplastic resin is one or more of polyaryletherketone, polyetheretherketone or polyethersulfone Various.
[0020] b. Then, compound the other side of the single-layer fabric with thermoplastic resin prepreg in the above-mentioned part of the thickness area, and compound it with thermosetting resin. Thermosetting resin refers to double horse resin, epoxy resin, cyanate resin or One or more of polyimide...

[0025] Preparation of half-layer EW100A / epoxy resin matrix composite structure
[0026] a. First, use the single-layer glass fiber plain weave fabric EW100A (single-layer thickness 0.1mm) as a reinforcement, and adopt the method of compounding one side of the single-layer EW100A fabric with thermoplastic polyaryletherketone resin, through process control, in a single layer A thermoplastic polyaryletherketone resin prepreg is formed in the area of 1 / 3 nominal thickness of the layer EW100A fabric;
[0027] b. Then, still using single-sided composite method, through process control, epoxy resin prepreg is formed in the 2 / 3 nominal thickness area of single-layer EW100A fabric that is not composited with thermoplastic polyaryletherketone resin, and thermoplastic polyaryletherketone resin is obtained. Aryl ether ketone resin / epoxy resin laminated prepreg;
[0028] c. Secondly, the above-mentioned thermoplastic polyaryletherketone resin / epoxy resin laminated prepreg is used, and...
