GORE™ OMNIBEND™ Fiber - Technical Information


Extended Service Life

The Charts below illustrate extended service life of ropes using GORE™ OMNIBEND™ Fiber in braided and laid rope constructions.  The addition of GORE™ OMNIBEND™ Fiber dramatically increased cycles to failure.

 Performance Chart of Laid Rope

Tension Member Technology conducted bend over sheave testing of 6x9 Twaron® 3/4 inch Aramid yarn laid rope made by Whitehill Manufacturing Corporation.  Ropes were constructed with and without GORE™ OMNIBEND™ Fiber. 

Test conditions: Load, 25% of break strength; cycle rate, 500 cycles/hour; speed, 1.1 ft/sec; D:d, 20; sheave, 15 inch.

 Performance Chart for Braided Rope

Tension Member Technology conducted bend over sheave testing of 12-strand 3/4 inch Vectran® LCP yarn braided rope made by Cortland Cable.  Ropes were constructed with and without GORE™ OMNIBEND™ Fiber. 

Test conditions: Load, 18.5% of break strength; cycle rate, 500 cycles/hour; speed, 1.1 ft/sec; D:d, 20; sheave, 15 inch.

Reduced Rope Operating Temperatures

GORE™ OMNIBEND™ Fiber dramatically reduces the rope surface temperature during operation. 

Rope temperature performance chart

Tension Member Technology monitored the rope surface temperature during the bend over sheave testing.  The 12-strand 3/4 inch Vectran® LCP yarn braided ropes made by Cortland Cable were constructed with and without GORE™ OMNIBEND™ Fiber. 

Test conditions: Load, 18.5% of break strength; cycle rate, 500 cycles/hour; speed, 1.1 ft/sec; D:d, 20; sheave, 15 inch.
