Abstract
A methodology for obtaining a full carbon fiber reinforced polymer double bend putter shaft wherein the summation of the two bending angles is 9 degrees is disclosed herein. Starting pre-resin impregnated unidirectional carbon fiber reinforced polymers are sectioned into ply patterns and wrapped on mandrel. The wrapped mandrel is placed in a furnace to elevate the viscosity of the resin for bending on a pipe bender, followed by heating and curing vertically.
