Effect of Fibre Length and Fibre Weight Percentage on the Hardness and Absorption Properties of Sisal, Ramie Fibre Reinforced Hybrid Polymer Composites

A study of hybrid polymer composites reinforced with ramie and sisal fibres is being conducted to investigate how fibre length and fibre weight percentage affect their properties. Compression moulding machines were used to prepare hybrid polymer composites. A total of four different lengths of fibre and four weight percentages of fibre were used in this experiment, with a variation of 10, 15, 20, and 25 mm. On a Shore D scale, the sample ranged from 64 to 92. In water absorption and chemical absorption tests, the sample was able to resist up to 16.2% of the absorption characteristics. Using the scanning electron microscope, we examined fiber de-bonding and pull-out from matrix materials. This study allowed identification of the optimal fibre reinforcement length and weight percentage for lightweight materials applications, as well as the ideal hybrid polymer composite length.
