Unique Composite Tube Manufacturing Process

North Thin Ply Technology (NTPT™) has launched a unique composite tube manufacturing process. Whilst the first application of this process is in Olympic medal-winning golf shafts, having been used by professional golfer Lydia Ko to win her silver medal at the Rio 2016 Olympic Games, the innovative process is ideal for any tubular structure where weight, performance and cost are critical factors.

This patent-pending process, which combines precise control of the fibre lay-up angles and the enhanced properties of NTPT™ Thin Ply prepregs, has enabled the first major technological development in golf shaft manufacturing since the mass adoption of graphite golf shafts in the 1980s.

The micro-structure of a thin ply laminate results in higher mechanical properties. Within a golf shaft, or any other tubular product, the use of thinner plies offers nearly unlimited options for fibre angles and fibre type combinations. NTPT™’s novel process ensures that each of the carbon plies is laid concentrically, resulting in a symmetrical shaft (or tube) with no spine, unlike the traditional table rolling production methods that have dominated the golf market until now.

The process also enables precise control over the ratio of longitudinal plies to off-axis plies along the length of the shaft.  The resulting uniformity of wall thickness and control of fibre alignment provides a smoothly changing flex profile, matching the design exactly.

NTPT™’s novel composite tube manufacturing process sees its first commercial application on the golf course, under the brand name TPT Golf™. The overall potential of this innovative manufacturing technology is, however, considerable. Automotive drive shafts, aircraft struts, windsurf masts, as well as other sports equipment shafts and frames, are just a few examples of other possible applications.

NTPT™ will exhibit at JEC World 2017, Paris 14th - 16th March.
