Lower Shaft Deformation = Higher Accuracy

The introduction of the Shotmaker insert made it possible for golfers to see with his/her eyes how lower shaft deformation contributes to higher accuracy.  The publicity surrounding this invention certainly gave shaft designers everywhere additional reasons to pay close attention to minimizing shaft deformation.hs_shotmaker_300x250_static_101211a_1318443091_300_01

When surveying techniques used to reduce shaft deformation in the industry, it is quite evident that the common approach was to wrap a portion of the golf shaft with a layer of woven graphic fabric of some sort, hoping it will somehow reduce shaft deformation.  The magical power of graphite fabric seems to lie within the number of axis of the weave: the more axes, the better.  Therefore, the trend is to use graphite fabric with increasing number of axes in the weave.

Graphite fabric is weaved in machine similar in construction to one used to weave regular fabric.  The more graphite tows used to make it, the thicker the fabric is.  Woven fabric is naturally porous, as compared to a sheet of densely laid out unidirectional graphite prepreg.  The wall thickness of a graphite shaft is highly valuable and must be used by its designer prudently as to yield the highest performance.

The question is how can a relatively thick fabric that is porous in nature be the material of choice to reduce shaft deformation or to make any high performance golf shaft.
