Abstract
A continuous carbon fiber composite filament impregnation pretreatment device includes a conveying assembly. The conveying assembly is arranged on a pretreatment device frame. Adhesive layer spray assemblies are provided on left and right sides of the conveying assembly. A plurality of multi-angle cleaning assemblies is sequentially arranged at a front end of the pretreatment device frame. The device overcomes the defects in the impregnation of a continuous fiber reinforced composite filament by pre-treating the surface of the filament and then spraying a thermoplastic adhesive layer onto the fiber surface during the fiber spreading process before impregnation treatment.
