Design Of Engine Components With Thermoresistant Composite Material The twenty-first century was characterized by an increasing demand in terms of technology progress, from the informatic field to the automotive one. Regarding the automotive field, in the last years global pollution became more and more important and, with this in mind the engine efficiency and the fuel saving have concentrated on themselves the efforts of the fabricants. The project is based on the usage of composite materials in the automotive field. In order to reach this goal, FEM (Finite Element Method) analyzes have been performed on different engine components. In particular, this project focus on the wrist pin, between the piston and the connecting rod.
