Abstract: A method is provided for designing and producing fiber-reinforced polymer (FRP) pistons. Pistons made with FRP have a lower mass than prior art metal pistons conferring advantageous engine efficiency and stability. FRP pistons also increase the thermal efficiency of engines by having a lower thermal conductivity, with tighter piston-to-bore clearance, and/increased air-fuel ratio than pistons of metal. The technical parameters of the piston are identified, and a piston body blank is produced. The blank is then machined, a bearing surface for the pin bore is created, the piston blank is optionally coated, is optionally subjected to Heavy Metal Ion Implantation (HMII) treatment and is subjected to sodium silicate impregnation to produce the final pistons.

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.

Abstract: Methods of designing and producing a connecting rod using carbon fiber reinforced epoxy molding compound composite material are provided, such that the method allows connecting rod designer to machine several different connecting rod designs, lengths, and beams. The material is molded into a near-net shape. After molding, the blank is machined into the final shape of a connecting rod and the material is sealed.
