Fibers typically control the strength and stiffness characteristics of the laminate.
The matrix is the binder that contains the fibers and transfers loads to the fibers, the latter being the most significant. Therefore, a low strength matrix or a poor fabrication process will yield a higher product design failure rate, particularly in the compressive mode. From an engineering standpoint, when we say failure rate we don't necessarily mean breakage, but that the golf shaft may not behave as designed, in reference to stiffness, torque and tip or butt flex. The uni-tape is then cut in patterns and arranged in certain angles of orientation, so as to yield a golf shaft that exhibits certain mechanical behaviors that the engineer designer is seeking. These patterns are referred to as flat patterns and are the most common fabrication process in the manufacturing of golf shafts today.
