Abstract: A method is provided of designing and producing a carbon fiber composite wrist pin using a combination of a carbon fiber composite pultruded rod that is overwrapped with a carbon fiber prepreg fabric. The use of the carbon fiber pultruded rod and the carbon fiber prepreg fabric results in a rod with optimal flexural strength properties to endure the flexural stress placed on a wrist pin during the cycling of an internal combustion engine. In addition, the overwrapping of the pultruded rod with a carbon fiber prepreg fabric allows for one pultruded rod blank to produce multiple wrist pin sizes by allowing one to change the outer diameter of the wrist pin by changing the thickness of the carbon fiber prepreg fabric overwrapping. After overwrapping, the rod blank is cut to a chosen specific length, optionally inserted into a metal sleeve, and coated with a thermal barrier coating. The wrist pin is then ground to a chosen specific tolerance and coated with an anti-friction coating.
