Step 3: thermoplastic material is added in extruding machine, will by extruding machine by heating thermoplastic material to semifluid shape
The thermoplastic material of semifluid shape is overlying on the surface of core wire, forms the internal layer；
Step 4: after internal layer cooling and shaping, including the first continuous fiber reinforced thermoplastic resin prepreg tape spiral winding
The surface of layer, heats the first continuous fiber reinforced thermoplastic resin prepreg tape, so that the first continuous fiber reinforcement thermoplastic
Thermoplastic resin in property resin prepreg band is in molten state, and after cooling and shaping, the first continuous fiber reinforced thermoplastic resin is pre-
Leaching band closely overlays on the outside of internal layer；
Step 5: the thermoplastic material of semifluid shape is overlying on by the preimpregnation of the first continuous fiber reinforced thermoplastic resin by extruding machine
The surface of band forms middle layer；
Step 6: after the cooling and shaping of middle layer, the second continuous fiber reinforced thermoplastic resin prepreg tape is spirally wound on
The surface of layer, heats the second continuous fiber reinforced thermoplastic resin prepreg tape, so that the second continuous fiber reinforcement thermoplastic
Thermoplastic resin in property resin prepreg band is in molten state, and after cooling and shaping, the second continuous fiber reinforced thermoplastic resin is pre-
Leaching band closely overlays on the outside in middle layer；
Step 7: the thermoplastic material of semifluid shape is overlying on by the preimpregnation of the second continuous fiber reinforced thermoplastic resin by extruding machine
The surface of band forms outer layer；
Step 8: it is cooling that the product of step 7 is subjected to water；
Step 9: product after cooling is wound into disk.
8. production method according to claim 7, which is characterized in that in the step 4, increase to the first continuous fiber
While strong thermoplastic resin prepreg tape is heated, also internal layer is heated.
9. production method according to claim 7, which is characterized in that in the step 6, increase to the second continuous fiber
While strong thermoplastic resin prepreg tape is heated, also middle layer is heated.
