Definitions
- the embrittlement coefficient makes it possible to take into account the loss of efficiency of the cable in traction due to transverse embrittlement in the inter-son contacts at the level of the outer metal son of the inner layer and of the outer layer.
- This embrittlement coefficient depends on the number of external metal wires of the internal layer, on the contact angle between the internal strand and the or each external strand, on the diameters d3 and d3 'respectively of the external metal wires of the internal layer and of the outer metal wires of the outer layer, the helix angle of an outer strand, and the breaking force of an outer strand.
- a solid cable will have an embrittlement coefficient close to 1 and an embrittled cable will have a non-optimal embrittlement coefficient, rather close to 0.5.
- the cables of the state of the art have either a relatively high breaking force but a not optimal embrittlement coefficient, or an optimal embrittlement coefficient, that is to say close to 1 but. relatively low breaking force like example 8 of WO2016017655.
- the cables of the state of the art have a relatively low surface breaking energy.
- the cable according to the invention due to its relatively high embrittlement coefficient and its breaking strength, exhibits a relatively high elongation at break as well as a relatively high surface breaking energy.
- ES ⁇ 160 N. mm -1 preferably ES ⁇ 165 N. mm -1 and more preferably ES ⁇ 170 N. mm -1 .
- the embrittlement coefficient Cfrag takes into account the penetration of the cable by the polymer matrix using the inter-strand penetration coefficient Cp.
- a cross section of the cable extracted with a saw is made. This operation is repeated ten times to obtain ten cross sections on which we will calculate an average penetration coefficient Cp.
- the filling zones of the polymeric composition of each extracted cable are then observed under an electron microscope by quantifying, using an image processing software, the ratio of the non-metal surface without polymeric composition to the surface filled with polymeric composition. in the Sep contact zone shown in figure 8 between the outer strands and the inner strand.
- a well penetrated cable will have a penetration coefficient close to 1 and a less well penetrated cable will have a penetration coefficient close to 0.5.
- the composition comprises the mixture and / or the reaction product in situ of the various constituents used, some of these constituents being able to react and / or being intended to react between them, at least partially, during the various phases of manufacture of the composition; the composition may thus be in the fully or partially crosslinked state or in the non-crosslinked state.
- the interwire distance of the outer layer of the inner strand is less than or equal to 100 ⁇ m.
- the sum SI3 of the interwire distances I3 of the outer layer of the inner strand is greater than the diameter d3 of the outer yarns of the outer layer.
- FIG. 4 is a schematic sectional view perpendicular to the cable axis (assumed rectilinear and at rest) of a cable (50) according to a first embodiment of the invention
- FIG. 5 a schematic sectional view perpendicular to the cable axis (assumed rectilinear and at rest) of an extracted cable (50 ’) according to a first embodiment of the invention
- the cable 50 also includes a hoop F, not shown, consisting of a single hoop wire.
