Study of agriculture wasted of rice paddy pulp reinforced epoxy for the used composites sheet materials

Abstract

ABSTRACT The rice paddy is an important lingo cellulose fibre used for making a variety of floor-furnishing materials and rope etc. But it contributed to a very small percentage production of rice paddy. So, researchers are trying to find new areas for the utilisation of rice paddy as in reinforcement polymer composites. The rice paddy in different reinforcement ratios is used to produce hand lay-up composite materials. The produced composite samples were then characterised using tensile tests, compressive test and Izod impact tests. The fracture surfaces of the reinforced composite samples were inspected with the help of SEM. The contents of rice paddy pulp vary (35%, 45%, 55%) in weight percentages, whereas the percentages of epoxy resins vary (50%, 40%, 30%) that are kept constant (15%) in hardener. All the samples were tested in the universal testing machine as per the ASTM standard for tensile strength, compressive strength and impact strength. It is observed that composite with 35% paddy pulp is having the highest tensile strength of 4 mm (4.34 MPa) and 8 mm (6.02 MPa). The impact strength of composite with 35% rice paddy pulp was higher than 45% to 55% rice paddy pulp.
