A method for manufacturing a hoisting rope, the method comprising:
- providing a plurality of elongated composite members, each elongated composite member of the plurality of elongated composite members including a composite material, the composite material including reinforcing fibers embedded in a polymer matrix;
- arranging the plurality of elongated composite members to form an elongated row of parallel composite members such that the elongated row of parallel composite members includes the plurality of elongated composite members, the elongated row of parallel composite members having a longitudinal direction, a thickness direction and a width direction, wherein, in the elongated row of parallel composite members, the plurality of elongated composite members positioned side by side in the width direction such that the plurality of elongated composite members extend in parallel in the longitudinal direction of the elongated row of parallel composite members and are spaced apart at a particular distance in the width direction of the elongated row of parallel composite members, wherein
- each elongated composite member of the plurality of elongated composite members is substantially larger in the width direction of the elongated row of parallel composite members than in the thickness direction of the elongated row of parallel composite members and includes
- two opposite sides facing in the thickness direction of the elongated row of parallel composite members, and
- two opposite sides forming flanks facing in the width direction of the elongated row of parallel composite members, and
- each flank of said each elongated composite member of the plurality of elongated composite members has a convex shape,
- wherein the arranging of the plurality of the elongated composite members to be positioned side by side in the width direction, is performed by guiding said each elongated composite member under tension;
- directing plasma treatment on the elongated row of parallel composite members and thereby on one or more outer surfaces of said each elongated composite member of the elongated row of parallel composite members while continuing the guiding to keep the elongated composite members spaced apart at the particular distance in the width direction;
- embedding the plurality of elongated composite members of the elongated row of parallel composite members in fluid polymer material while keeping the elongated composite members spaced apart at the particular distance in the width direction, subsequently to the directing the plasma treatment, to establish a product having the plurality of elongated composite members embedded in the fluid polymer material where the elongated composite members embedded in the fluid polymer material are positioned side by side with said each elongated composite member spaced apart at the particular distance in the width direction;
- and
- solidifying the fluid polymer material of the product to form the hoisting rope.
