Studies on mechanical and dynamic mechanical properties of banana fibre nonwoven composite

Abstract

Using banana fibre nonwoven reinforcement composite nine samples were produced by changing three different fibre lengths such as 4 cm, 6cm and 8 cm and three different volume fraction such as 20%, 30% and 40% of the total volume of the composite. Mechanical studies and DMA analysis have been done to measure the impact of fibre length and fibre volume fraction. It was found that up to 6 cm fibre length banana reinforcement the mechanical strength of the composite was increased and then decreased. Similarly, up to 30% fibre volume fraction, the mechanical strength of the composite was increased. Similarly in the case of DMA studies storage modulus and loss modulus were increased when the fibre volume fraction increases up to 40% and the loss factor was shown a negative trend when the reinforcement filling increases. In the case of fibre length 6 cm fibre reinforced banana fibre reinforced composite shown higher storage modulus and loss modulus but the loss factor was reduced when the fibre length of the reinforcement increases.
