Preparation method and device of continuous carbon fiber reinforced polyaryletherketone wire for 3D printing

The invention relates to the technical field of composite material preparation, in particular to a preparation method and device of a continuous carbon fiber reinforced polyaryletherketone wire for 3D printing. The method comprises the following steps: carrying out mid-infrared heating treatment on a thermoplastic pre-impregnated slit tow to obtain a first wire material in a molten state; the first wire is subjected to high-temperature bending treatment, and a second wire in a bent state is obtained; the second wire is subjected to high-temperature pultrusion treatment, and a cylindrical thermoplastic wire is obtained; wherein the thermoplastic pre-impregnated slit tows are continuous carbon fiber reinforced polyaryletherketone thermoplastic wires. The device comprises an unwinding system, a high-temperature heating furnace, a high-temperature wave-shaped curve mold, a high-temperature pultrusion mold, a traction system and a winding system which are sequentially distributed in the advancing ...
