Embodiment 1
[0017] A carbon fiber composite plate molding process, comprising the following steps:
[0018] a. Lay-up: Lay the carbon fiber filaments in parallel on the lamination plate of the flat vulcanizing machine in the way of horizontal → vertical → horizontal. The ratio of the number of layers of the carbon fiber filaments in the horizontal direction and the vertical direction is 8: 7, and the carbon fiber filaments are 8K fibers Silk.
[0019] b. Glue brushing: Use a roller to repeatedly brush epoxy resin on the surface of the layup. The carbon fiber filaments are completely absorbed by the epoxy resin, and the excess epoxy resin is exported. The ambient temperature for epoxy resin coating is 35°C .
[0020] c. Pressing: Continue to pressurize the carbon fiber filaments after brushing to 12MPa, and keep the pressure for 3 hours to make it a carbon fiber composite board with uniform thickness.
[0021] d. Curing: heating and curing the pressed carbon fiber composite panel. The h...
Embodiment 2
[0024] A carbon fiber composite plate molding process, comprising the following steps:
[0025] a. Layup: On the laminate of the flat vulcanizer, carbon fiber filaments are laid in parallel in the way of horizontal→vertical→transverse layup. The ratio of carbon fiber filaments in the horizontal and vertical layers is 8: 7, and the carbon fiber filaments are 16K fibers. Silk.
[0026] b. Glue brushing: Use a roller to repeatedly brush epoxy resin on the surface of the layup. The carbon fiber filaments will completely absorb the epoxy resin, and export the excess epoxy resin. The ambient temperature for epoxy resin coating is 45°C .
[0027] c. Pressing: Continue to pressurize the carbon fiber filaments after brushing to 12MPa, and keep the pressure for 4 hours to make it a carbon fiber composite board with uniform thickness.
[0028] d. Curing: heating and curing the pressed carbon fiber composite panel. The heating temperature is 260° C., and the heating curve is 15° C. / hou...
Embodiment 3
[0031] A carbon fiber composite plate molding process, comprising the following steps:
[0032] a. Layup: On the laminate of the flat vulcanizer, carbon fiber filaments are laid in parallel in the way of horizontal → vertical → horizontal. The ratio of the number of layers of carbon fiber filaments in the horizontal and vertical directions is 8: 7, and the carbon fiber filaments are 24K fibers Silk.
[0033] b. Glue brushing: Use a roller to repeatedly brush epoxy resin on the surface of the layup. The carbon fiber filaments are completely absorbed by the epoxy resin, and the excess epoxy resin is exported. The ambient temperature for epoxy resin coating is 50°C .
[0034] c. Pressing: Continuously pressurize the carbon fiber filaments after brushing to 12MPa, and keep the pressure for 5 hours to make it a carbon fiber composite board with uniform thickness.
[0035] d. Curing: heating and curing the pressed carbon fiber composite panel. The heating temperature is 280° C., ...
