TBAR Part 6

TBAR™ Part 6 of 6 TBAR™ with Zone Flex™ (‘Z’) Characterization By Carter Penley In TBAR Part 5, we discussed that one of the major problems in the golf shaft industry is that the standard flex range is dynamically much larger and in many cases overlaps corresponding flexes. This is why some players who may […]

Incorporating Cyclic Fatigue Testing TBAR – Part 5

TBAR™ DSO Incorporating Cyclic Fatigue Testing – Part 5 By Carter Penley The last ‘TBARtm” article (Part ‘4’) discussed the affects of the composite materials and geometric shapes on ‘TBARtm” measurement, with more emphasis on materials.             Part’4′ ended with the discussion concerning lightweight shafts; specifically the effects of the measurement equipment in reference to […]

TBAR Part 4

TBAR™ – Computer Design Program / CAD Shaft Laminate Schedule Part 4 By Carter Penley   Part 3 of TBAR’s series ‘Measurement and Method Of‘’ described the analysis and design solution process required to produce the empirical data to support the “TBAR™ hypothesis. The next phase was to correlate the composite materials and geometric profiles […]

TBAR Part 3 – Measurement and Method

TBAR™ – Measurement and Method Part 3 By Carter Penley As discussed in TBAR Part 2 – “The Art of Golf Shaft Measurement“, kick point is not the best measurement to determine a golf shafts ability to contribute to a golf clubs launch angle. For one thing, how is kick point measured?  (See TBAR vs. […]

TBAR – An Introduction

An Introduction to TBAR ™ By Carter Penley   Over the years of designing composite golf shafts I have had the opportunity to analyze golf shaft failures ‘structural, physical, mechanical and design anomalies.   Of the above mentioned failures design anomalies are the most difficult to dissect and analyze unlike structural and or mechanical failures […]

TBAR Part 2 – The Art of Golf Shaft Measurement

TBAR™ – The Art of Golf Shaft Measurement Part 2 By Carter Penley   Through the years there has been a quest by many to define a golf shafts performance or the ability to fit a player by some simple magic black or white number or method. Some like to know how fast a player […]

TBAR vs. Kick Point Part 1

TBAR™ vs. KICK (BEND) POINT Part 1 By Carter Penley The term “kick point”, originally referred to as bend point, has been a popular term for many years by many shaft manufactures and yet the most misunderstood and least useful term applied to the performance criteria of a golf shaft. I once heard it summed […]
