Abstract
A cable contains filaments containing carbon, surrounded by a sizing. The filaments surrounded by the sizing are covered by a matrix which is composed of a material containing at least one elastomer and/or at least one thermoplastic elastomer. The cable can be used, in particular for pulling a load, for example in a goods lift.
Claims31
A cable, comprising:
- carbon-containing filaments;
- a sizing surrounding said filaments, said sizing containing at least one material selected from the group consisting of polyurethanes, thermoplastic elastomers, polyesters, rubbers, rubber derivatives and any combination of at least two of the preceding compounds;
- a matrix covering said filaments surrounded by said sizing, said matrix composed of a material containing at least one of an elastomer or at least one thermoplastic elastomer;
- individual ones of said filaments surrounded by said sizing are untwisted with one another;
- at least 50% of said filaments surrounded by said matrix are carbon fibers;
- and
- a sheathing enclosing said matrix.
