Abstract: Due to a wide range of benefits such as high specific strength and stiffness, fatigue characteristics, and corrosion resistance, advanced fibre polymeric composites are one of the most successful composite material systems. Because the polymer matrix is more vulnerable to these changes than the fibre, the mechanical behaviour of FRP composites is dominated by the matrix. Polymers are visco-elastic materials, meaning their mechanical characteristics are affected by strain rate. The goal of this experiment is to find out how alkali treated chopped palm leaf stalk natural fibre polymer composites behave mechanically. Hand layup is used to create the samples, and the weight proportion of matrix and fibre is maintained between 30% and 70%. For various studies such as tensile testing, flexural testing, impact testing, and hardness testing, specimens are sliced from the produced laminate according to ASTM standards. A computerised Universal testing equipment, a Charpy Impact tester, and a Hardness tester are used in the experiments. The results demonstrate that, with the exception of hardness value, the trend in all characteristics rose for alkali treated chopped fibres.
