A thermally conductive rope includes a plurality of tows of crystalline carbon fiber, a plurality of tows of additional fiber, and at least one of a thermoset and thermoplastic.

A method for impregnating strands or strips of natural fibres, using the following successive steps: i) the impregnation of the strands or strips by immersion in a bath containing a fine aqueous polymer dispersion; followed by ii) the drying of the strands or strips using a heating system, with the progressive elimination of the water and the gradual melting of the polymer, and the coating of the strands or strips and the molten polymer incorporated into the core of the strands or strips as a binder between the fibres; iii) optionally, the forming of the treated strands or strips into their final shape; and iv) the cooling of the treated strands or strips. The aqueous polymer dispersion comprises at least one semi-crystalline or amorphous polymer and, in the case of an amorphous polymer, has a Tg varying between 50 C. and 175 C.

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.
