Effect of Erosive Wear on Pineapple Leaf Fiber Reinforced Vinylester Based Hybrid Composite as Acoustic Barrier

Abstract

Composites of natural fibre are subjected to rigorous study due to their environmental friendly properties. These natural fibres have the advantages of uninterrupted supply, and recyclable nature. Even though natural fibres reveal commendable physical and mechanical properties, it varies with the plant origin, species, geography, and so forth. Pineapple leave fibre (PALF) is one of the copiously available waste of agricultural resources in India and has not been studied yet. The present effort has been carried out to investigate the application of Pineapple Leaf fiber reinforced Vinylester based hybrid composites in acoustic barrier when the condition is wear driven. The obtained results are compared with a similar set of glass fiber reinforced Vinylester based hybrid composites. It is evident that the values of Sound Pressure level (SPL) obtained in case of a Single cylinder 4S petrol engine, Vertical 4-S Diesel Engine[2][4][7] and Air Compressor shows that the reduction in SPL can be achieved in its vicinity with maximum reduction at 1.5m from the source and a minimum reduction at 0.5m from the source for Pineapple leaf fiber (PALF) - Vinylester composites, thus after conducting the study we can say that the composites used can be recommended as a noise barrier also, and if the condition is erosion driven the composite material can sustain its property of reducing the Sound Pressure Level (SPL) dominantly and thus avoiding the sound levels.
