Embodiment 1
[0079] (1) Composite material layup:
[0080] 1) Mold preparation: use soft materials to wipe the mold cavity clean, and use liquid release agent to treat the surface of the mold for 6 times, with an interval of 10 minutes between each time;
[0081] 2) Cutting: Use an automatic cloth cutting machine to cut the glass fiber twill fabric prepreg with a protective film according to the size and shape required by the drawing, and pay attention to the type and fiber direction of the glass fiber twill fabric prepreg when cutting. Glass fiber twill fabric prepreg, the specification is 180g / m 2 , resin content 34%;
[0082] 3) Paving
[0083] ① Lower mold assembly: place the positioning boss 9 on the lower inner core 3 in the positioning groove 8 on the lower outer mold 1, and the bolts pass through the bolt holes 7 to fix the lower outer mold 1 and the lower inner core 3 together;
[0084] ② Lay glass fiber twill fabric prepregs of different sizes on the concave surface of the low...
Embodiment 2
[0100] (1) Composite material layup:
[0101] 1) Mold preparation: use soft materials to wipe the mold cavity clean, and use a liquid release agent to treat the surface of the mold for 5 times, with an interval of 15 minutes between each time;
[0102] 2) Cutting: Use an automatic cloth cutting machine to cut the carbon fiber plain weave fabric prepreg with a protective film according to the size and shape required by the drawing, and pay attention to the model and fiber direction of the carbon fiber plain weave fabric prepreg when cutting.

[0104] ① Lower mold assembly: place the positioning boss 9 on the lower inner core 3 in the positioning groove 8 on the lower outer mold 1, and the bolts pass through the bolt holes 7 to fix the lower outer mold 1 and the lower inner core 3 together;
[0105] ② Lay carbon fiber plain weave fabric prepregs of different s...
Embodiment 3
[0121] (1) Composite material layup:
[0122] 1) Mold preparation: use soft materials to wipe the mold cavity clean, and use liquid release agent to treat the surface of the mold for 4 times, with an interval of 30 minutes between each time;
[0123] 2) Cutting: Use an automatic cloth cutting machine to cut glass fiber twill fabric prepreg and carbon fiber plain weave fabric prepreg with protective film according to the size and shape required by the drawing, pay attention to the types of the two prepregs when cutting and fiber direction. Carbon fiber plain weave fabric prepreg, the specification is 200g / m 2 , resin content 40%, glass fiber twill fabric prepreg, specification 180g / m 2 , resin content 34%;
[0124] 3) Paving
[0125] ① Lower mold assembly: place the positioning boss 9 on the lower inner core 3 in the positioning groove 8 on the lower outer mold 1, and the bolts pass through the bolt holes 7 to fix the lower outer mold 1 and the lower inner core 3 together; ...
