         The History
And Evolution of the Carbon
Vaulting Pole and FX Design
                 Overview
• If you stop looking to improve will the
  competition do the same?
• In what sport would the preferred mode be
  twenty year old methods and technology?
• Carbon Fiber
• Probing the basic design ( leads to FX)
• Probing the material properties envelop
• Testing at the Plant – Data
• Using the tools – Vaulting
• Right tool for the right person
Stroll through Gill Athletics, Inc. and a short history of poles
1918 – Harry Gill starts making track and field equipment
1949 - Herb Jenks and his first fiberglass pole
1951 – Fiberglass poles carried in a track equipment booklet
1951 – Giltal Vaultmaster Metal Poles
1960 – Gill Fiberlite (fiberglass pole) carried steel, bamboo and fiberglass poles
1966 – Gill Big Red Fiberglass pole
1967 – “New in 1967” Training Poles – also 16’ Big Red’s
1967 – Rankin Method – weight rating versus hand hold height for fiberglass poles
1976 – Gill Vaultmaster II brown fiberglass pole is being phased out and Gill is now
carrying Dark Blue Skypoles
1976 – Patent on Fiberglass Vaulting Pole issued, Herbert Jenks, Assignee, AMF
Incorporated. Bob Prideaux a pattern cutter at Pacer is still helping make poles at Gill
Athletics, Inc.
1984 – Skypole and equipment sold to Gill. Ralph Paquin is 1st Gill Employee trained on
Skypole manufacturing, Ralph is still working at Gill in Engineering Group.
1985 – A few Light Blue Skypoles had carbon material - prototyping
1987 – Pacer Line and equipment for building poles, Herb Jenks patent and technology
sold to Gill.
1988 – Gill is testing Carbon Skypoles
2001/2002 – FX (Functional Design) – 2003 Started looking at advanced materials
2008 – Oct 21 - Patent Issued on Carbon Weave Vaulting Poles
                        Carbon Fiber
•   Carbon fiber
     – 1958, Dr. Roger Bacon created high-performance carbon fibers at the
        Union Carbide Parma Technical Center, located outside of Cleveland,
        Ohio
•   PAN aerospace/high end carbon fiber
     – polyacrylonitrile
•   Advantages
     – weight-to-strength ratio
     – extremely low flex fatigue over time
•   Disadvantages
     – Higher cost
     – Lower elongation limit
•   Potential
     – Steeper stress strain curve
Carbon Fiber in Poles
Pattern books contain thousands of the early carbon poles designs including
      going from Skypole to the Pacer line – Carbon Skypole was first
          What was behind FX
• Pacer
  – Sail Pattern Design
  – Who uses this now
• What was the goal
  – Transition in wgt
  – Transition in length
• What was the result
  – Vault over 6m on a pole you just got?
•   Why would mandrel diameter go down when wgt rating goes up
•   This was a Pacer trait pre FX project
65 percent chord length
3D Modeling
     Tools to Understand Better
•   Video Taping
•   Arc Lines – Factory Vaults
•   Dynamic Testing
•   Dartfish Anaylsis Software
•   3D Solid modeling (SolidWorks)
    – Motion Capabilities
    – FEA Capabilities
     New Generation of Carbon
•   2003 to the present – first was a treat
•   NCAA Champ’s
•   Medalist on World Stage
•   WJR, National Records
•   2009 EIC Champ
•   Just another step in the continued quest
    for improvement
                Mikko Latvala feedback
•   Comparison between Pacer FX, Carbon FX and Carbon Weave.
•    Best results with different models. In brackets is best result, biggest pole and lenght I have used with each model.
    At the end there is year when I have done it.
•   Old Carbon 566 (13.7/5.00m) -01
•   Carbon FX 560 (14.4/5.10m) -02
•   Carbon FX 560 (13.7/5.00m) -05
•   Pacer FX 563 (14.6/5.00m) -08
•   Carbon Weave 550 (14.3/5.00m) -09
•   Weight:
•   Weave feels very light, a little bit lighter than Carbon FX but big difference to Pacer FX. It is much easier to control
    my run up and planting with Weave.
•   Bending:
•   Even my take off is not so good and I have quite low grips(4.80-4.90), weave started to bend quite easily. It felt
    ”softer” in take off than Carbon FX. Weave and Pacer FX are quite close each other at take off but what makes it
    easier is the weight of the pole.
•   I think Weave has the best bend, it is more circular than Carbon FX and Pacer FX. I think weave is not so exact
    for take off angle. Even if vault is moving forward is a little bit low, it still bend very circular. (if you understand what
    I am meaning)
•   Recoil:
•   I think Pacer FX has slowest recoiling of these three models. Weave and Carbon FX has quite similar recoil. But
    anyway all these three models has quite fast recoil. I did one pv session with 14.9/500 spirit pole and its recoil was
    much slower than weave´s.
•   I used Weave poles only twice in Chula Vista, so experiences are mostly from one competition I did there.
      What works for the vaulter
•   The right tool
•   F1 versus limo
•   Beginner versus elite
•   One pole versus various poles
    – Different lengths
    – Different ratings or flexs
    – Different Designs
Questions?
