Embodiment 1
[0027] Such as Figure 1 to Figure 3 Shown, a kind of degradable carbon felt prepreg manufacturing process is characterized in that, comprises the steps:
[0028] Step 1. Add component A of RAF-901 resin to the serial mixer at 900-1200 rpm;
[0029] Step 2: Add component B thickener into the serial mixer and stir evenly to obtain epoxy resin paste;
[0030] Step 3: Clean up the RFRT sheet material machine, prepare the PP film, add the mixed epoxy resin paste to the upper and lower glue tanks, turn on the equipment, apply the epoxy resin paste to the inner surface of the upper and lower PP film, and then Composite with chopped carbon fiber mat;
[0031] Step 4: pressurize again, impregnate the carbon fiber felt with resin, and then wind up the resin-impregnated carbon felt with a 6-10-inch inflatable shaft;
[0032] Step 5. Put the carbon fiber felt sheet material prepared above into the drying room for thickening and aging treatment. After the aging treatment is completed, ...
