ABSTRACT
Composite materials made of natural fibers are becoming more and more popular as a result of the need for environmentally friendly and sustainable materials in the furnishing and construction sectors. Because of their low cost, high mechanical and physical qualities, and renewable nature, bamboo and coir fibers in particular have shown great potential. We treated and delignified fresh bamboo culms with a 0.1M sodium hydroxide solution. The delignified and dried bamboo was turned into powdered fiber. Composite samples for experiments were created by combining bamboo fiber with coir fiber and an epoxy matrix. In order to arrange the tests and optimize the operating conditions (i.e., factor levels of the input variable) of the created composite with respect to the projected response parameters, a mixed experimental design was used in the study, with three variables acting as mixture components. Tensile stress, modulus of elasticity, thickness swelling, and water absorption were all predicted using models. Based on the acquired data, the composite that was formed had an optimal proportion mixing of 42.2% bamboo fiber, 35% epoxy, and 22.8% coir fiber. Tensile stress, modulus of elasticity, swelling, thickness, and water absorption values for the composite that resulted from this mixture were 1.068 MPa, 694.450 MPa, 1.850%, and 20.800%, respectively. It is advised to use the composite since it has generally favorable mechanical and physical qualities.
