The bonded macro fiber composite (MFC) and woven kenaf effect analyses on the micro energy harvester performance of kenaf plate using modal testing and Taguchi method
A. Hamdan, F. Mustapha
The number of wind energy applications will continue to increase as fossil fuel reservoir keeps decreasing. More researches are recently conducted to employ a green material concept for turbine blades. The usage of natural fiber reinforced composite, especially kenaf fiber, in the fabrication of wind turbines needs to be given due attention. Woven and unwoven kenaf fiber is employed to fabricate composite plates which replicate the simple turbine blade model. In addition, Macro Fiber Composite (MFC) is attached to the kenaf plates for structural health monitoring and micro energy harvester purposes. The MFC used is attached with two techniques which are surface bonded and embedding into the plate. The modal testing analysis and Taguchi method is employed to investigate the effects of attached MFC technique. Bonded technique is suggested as the most influenced factor in micro energy harvesting at the vibration range of 20 to 60 Hz. Furthermore, the kenaf woven type, the distance from structure neutral axis, the stiffness of structure, the excitation vibration and the neutral frequency of a structure are highlighted as the factors influencing the performance of micro energy harvester.
