Abstract


The today’s research trend in composite is for the development of composite with natural fibre instead of synthetic fibre. It is because of properties like low cost, light weight, bio-degradability, ease to manufacture and low impact on environment. It becomes necessary to study the vibrational behaviour of composite in addition to mechanical strength and chemical properties for effective utilization in real world applications as they subjected to many types of loading condition and different types of vibration with different configurations. In present work, Jute _ Epoxy (BD), Jute _ Polyester (BD), Jute (UD)  and Sisal (UD) as material whose beam are manufactured for measurement of transverse vibration with different end configuration and also compared with result obtained from analytical method and Artificial Neural Network results. The required mechanical properties are taken by performing tensile and flexural test on the beam according to ASTM standards. The vibration test is performed using system consisting Raspberry Pi3 Model B and accelerometer ADXL 345, which gives data based on time and measures the acceleration. To convert time domain data into frequency domain Fast Fourier Transformation (FFT) is done in MATLAB and natural frequencies are found out. Results are also compared with analytical results and with the results obtained by ANN using Matlab R2017a.
