Benefits of technology

The patent describes a new type of composite tube that has a hollow wall, which makes it strong and lightweight. This new tube is also resistant to vibration, meaning it can handle a lot of movement without getting damaged. Additionally, it can resist distortion when flexed, loaded, or exposed to torque. Basically, this new type of tube is perfect for use in a variety of situations where strength and lightness are important.

Problems solved by technology

When more strength is desired in a composite tube, options are limited.
Decreasing wall thickness to reduce weight can have catastrophic results.
A single unsupported wall is subject to distortion, vibration, buckling, even cracking and splitting.
Changing material can increase cost.

Embodiment Construction

[0018]FIG. 1 is a section view of a hollow wall composite tube in accordance with the invention. The section view in FIG. 1 is cut parallel to the axis of the tube. The hollow 4 shown is arched for strength, like an architectural arch. The shape of the hollow 4 can be tuned to optimize performance in a given application. For example, if the tube is to be used as a golf club shaft, subject to severe side loads, the arch shaped hollow 4 strengthens the wall against collapse.

[0019]FIG. 2 is a perspective view showing constituent tube 7 being wound onto a removable mandrel 5. Also shown is constituent tube 7 being produced by spiral wrapping core 6 with tow (filaments) or fabric 8 prior to being wound on mandrel 5. Tuning of the hollow 4 shape can be accomplished by changing the shape of core 6. An elongated oval core 6 will produce an elongated oval hollow 4 after curing in a manner well known to those skilled in the art, and core 6 is removed by dissolving or melting. Likewise a round...

Abstract

A one piece composite tube having a hollow wall structure. The outside and inside of the tube have a standard surface and shape for bonding or fastening. The hollow wall reduces vibration and allows consistent flexure and torsion. The shape of the hollow wall may be tuned to maintain light weight and optimize strength for a given application.
