Composite golf shafts consist of sheets of graphite material of varying weights and strengths that are cut to exacting dimensions and wrapped around a steel rod called a “mandrel”. The graphite is then vacuum wrapped and sealed before being heated to cure. Once cured, the mandrel is extracted leaving behind a graphite tube or shaft.
Graphite shafts are designed and built in a myriad of specifications including weight, flex, and bending profiles. The overall design and desired product performance outcome dictates which types and how much of certain materials are used.
