Fabrication and Investigation of Mechanical Performance of Polymer Based Golf Shaft

The Composite materials have found widespread applications in various fields of engineering such as aerospace, marine, automobile and mechanical applications. Polypropylene is most widely used polymer matrix composite (PMC) due to its unique strength and hardness. In sports application like golf shaft which is subjected to various deflection and torsion loads so that ordinary steel golf shaft is replaced to polypropylene plastics which may help the player for more comfort due to its weight reduction. The Composite structure of golf shaft made of polypropylene plastics is modeled and mechanical behavior is experimentally calculated. Experimentally deflection is measured by hanging a mass on the tip with the butt fixed. The degree of torsion is measured by applying the twisting moment, to the tip. The frequency of vibration is measured by adding a mass to the tip of a shaft and shaking it.Finite element results for deflection and torsion give satisfactory results with the experimental data. These results will be useful in designing polypropylene and sheet rolled golf shaft.
