Research on Enhancing Vehicle Fuel Efficiency Based on Custom Material Properties

This paper highlights the benefits of using carbon fiber, ceramics, titanium alloys, and aluminum alloys to replace traditional metals in the manufacture of automotive components. Carbon fiber is lightweight and of high strength and has a high impact absorption capacity. Its wide application will significantly reduce the weight of the vehicle, but there is a problem of high cost. Ceramics are hard and wear-resistant and can be used to manufacture parts that are directly subjected to alternating loads. Titanium alloy has high hardness but high density and can be used to manufacture key parts with high strength requirements. The aluminum alloy has high specific strength, but low fatigue strength and no wear resistance, so it can be used to manufacture parts that do not bear alternating loads such as frames. Furthermore, these materials possess a significantly lower density compared to conventional steel. They are reasonably applied to the manufacture of automotive parts, to ensure safety the same time can also significantly improve fuel efficiency.
