H -- ENGINEERING SERVICES AND TESTING OF ARAMID FIBER ROPES AND TROLLEYS FOR THE AERIAL CABLE RANGE SOL DAAD07-95-R-0104 DUE 022295 POC For information contact Edna T. Hakenson, Contract Specialist, at (5O5) 678-4936, or Norbert F. Dupre, Contracting Officer, at (5O5) 678-5134 The White Sands Missile Range, NM intends to acquire on the basis of Other Than Full and Open Competition, as prescribed by FAR 6.302-1, from Tension Member Technology, a three-year contract for the design, analysis, performance optimization, and cyclic testing of large diameter (2.5'') aramid fiber ropes, and related cable handling equipment. The proposed services will begin in March 1995. The ropes and cable handling equipment to be tested are being developed for potential use at the WSMR Aerial Cable Range. See Note 22 except that any responses must be received within fifteen (15) days after the date of this publication. Interested sources must provide convincing evidence of their experience, testing capabilities, and expertise involving large aramid fiber ropes and related handling equipment to this office within 15 days after the publication of this notice. The following is a brief description of the minimum requirements: 1) Existing cyclic-bending test machine capable of performing reverse-bend fatigue tests on aramid fiber ropes utilizing a government furnished (GF) test article fitting in a volume with dimensions, length = 22, width = 2.5., and height = 2 . Rope tension during these tests shall be a minimum of 100,000 pounds. The rope shall be cyclically stroked at a nominal rate of 48 ft/min and a stroke length of 24 . The test machine fixture which supports the test article shall be capable of safely supporting a rope induced moment of approximately 16,000 pounds and a rope induced towing force of 5, 000 pounds. 2) Existing cyclic-bending test machine capable of performing reverse-bend fatigue tests on aramid fiber ropes utilizing a GF test article fitting in a volume with dimensions, length = 10, width = 2.5, and height = 3 . Rope tension during these tests shall be a minimum of 100,000 pounds. The rope shall be cyclically stroked at a nominal rate of 48 ft/min and a stroke length of 12 . The test machine fixture which supports the test article shall be capable of safely supporting a rope induced towing force of 5,000 pounds. 3) Existing cyclic-bending test machine capable of performing reverse-bend fatigue tests on aramid fiber ropes utilizing a GF test article fitting in a volume with dimensions, length = 12, width = 5 and height = 3 . Rope tension during these tests shall be a nominal 150,000 pounds. The rope shall be cyclically stroked at a rate of 48 ft/min and a stroke length of 14 . The test machine fixture which supports the test article shall be capable of safely supporting a rope induced towing force of 5,000 pounds. 4) Existing tensile test machines with load capacities up to 400,000 pounds, capable of performing tension, elongation, torque, rotation and elongation to break tests. These machines shall utilize friction compensated swivels to eliminate swivel bearing friction. 5) Existing data acquisition equipment (e.g. strip chart recorders, x vs. y pen plotters, PC based acquisition) capable of collecting applicable data from the tests described above. 6) Existing technical expertise in installing potted socket end terminations on large diameter aramid fiber ropes capable of sustaining a minimum tension of 75% of the design break strength of the ropes. 7) Existing technical expertise in installing eye splice end terminations on 36 strand aramid fiber ropes capable of developing the full break strength of the rope. 8) Expertise in the dissection of aramid fiber ropes for the purpose of documenting rope designs and for post test failure analysis. Experience cited shall be primarily with Kevlar (a registered trade name of DuPont) ropes of diameters of 2 or greater. (0017)
