Abstract
A synthetic rope (20) comprises a core (22) and at least a first layer surrounding the core (22). The first layer has first layer strands (26). The core has a fluted outer surface with spaced apart helical concave grooves. Each of these grooves contacts one of the first layer strands (26). The grooves have a radius of curvature (24) that is greater than the radius of curvature (14) of a circle having a same diameter as the contacting first layer strand before twisting.

A synthetic rope comprising
- a core comprising a load bearing member and a core cover, and
- at least a first layer surrounding said core,
- said first layer having first layer strands,
- said core having a fluted outer surface with spaced apart helical concave grooves,
- each of said grooves contacting one of said first layer strands,
- said grooves having an actual radius of curvature that is greater than a hypothetical radius of curvature of a circle having the same cross-section as the cross-section of a first layer strand,
- said actual radius of curvature being the same throughout an entirety of said grooves,
- wherein the load bearing member of the core and the core cover of the core are made from different materials.
