Abstract
A great gain has been made in recent years in the creation of hybrid bio-composites by combining different natural resources as reinforcement and filler elements. The waste marble dust particles and tamarind shell powder particles were additional to the epoxy resin matrix in this experiment to study the tensile and flexural characteristics of the epoxy resin matrix. Tamarind shell powder and waste marble dust particles are used as reinforcing materials. To create hybrid bio-composite specimens, researchers varied the reinforcement material weight percentages while maintaining the epoxy resin weight percentage as constant. Hot injection moulding was used to create hybrid biocomposites boards. The hybrid bio-composite specimens for tensile and flexural tests are cut away from the hybrid bio-composite boards using the water jet machining method as per ASTM specifications. Research shows that adding small amounts of fine waste marble dust particles and tamarind shell powder to an epoxy resin matrix enhances the hybrid bio-composites' tensile and flexural capabilities significantly. The maximum tensile strength, yield strength, elongation percentage, flexural strength and flexural modulus of 34.63 MPa, 32.81 MPa, 3.3 %, 36.17 and 38.53 MPa were obtained from 35 wt% tamarind shell powder and 15 wt% waste marble dust powder composite specimens (C4 Composites) correspondingly.
