Natural Fiber Base Composite Material Solution for Vibration Damping of ICE and Next-Generation Vehicle 2023-01-0728

Vibration control plays a critical role in conventional as well as next-generation vehicles. Construction of the vehicle, road conditions, and driving patterns are the major sources of the vibrations that cause discomfort to the passengers in the vehicle. Composite material is being looked at as an alternative material in the automotive sector due to its higher specific strength and good damping properties. In this research, the test specimen of steel plate used in automotive has been considered. The damping vibration test has been carried out on the test specimen by using the FFT analyzer to evaluate the natural frequency and damping. Thereafter, the hybrid composite material is developed with the natural fibers as reinforcement with steel plate to reduce the vibrations. The test specimens with different layers of damping materials have been prepared for this research. Jute, hemp, banana, and flax are used for the preparation of different composite materials. This research has been further extended to vehicle-level applications like tyre, which is a common source of vibration in vehicle. Significant vibration reduction has been achieved by using natural fiber base composite materials and with different layers.
