Abstract
The invention includes a composite cable having a plurality of strands (10, 12) stranded around a composite synthetic core (5) with a concentric structure. The core (5) has a nucleus (11) formed by a bundle of parallel synthetic fibers extending along the cable longitudinal direction, and of a compact thermoplastic sheath (13) enclosing the nucleus (11) and serving as winding support for the strands.
Claims18
A composite cable comprising:
- a bundle of plural parallel synthetic fibers extending in a longitudinal direction of the cable forming a core of the cable;
- a deformable sleeve surrounding said core and being a thermoplastic material;
- and
- plural strands wound about and embedded in said sleeve.

A composite strand comprising:
- a bundle of plural parallel synthetic fibers extending in a longitudinal direction of the strand forming a core of the strand;
- a deformable sheath enclosing said core and being a thermoplastic material;
- and
- plural filaments wound about and embedded in said sheath.
1 more element
A composite cable for lifting a load, comprising:
- a bundle of plural parallel synthetic fibers extending in a longitudinal direction of the cable forming a core of the cable;
- a sheath of thermoplastic material surrounding said core;
- and
- plural strands wound on said sheath and exerting a radially inward force on said sheath so that said sheath deformably fills spaces between adjacent ones of said plural strands, and
- wherein said sheath exerts a radially inward force on said plural synthetic fibers so that a longitudinal deformation of said core is substantially equivalent to a longitudinal deformation of said plural strands when the cable is lifting a load.
