Abstract

The rapid growth of non-degradable plastics with poor management of waste is a major international challenge for the environment; thus, prompt development of high-performance sustainable materials is demanded. In this work, the epoxy-based composites reinforced by waste cotton fabric and clay powder were developed to improve mechanical and thermal properties for home furniture. The impacts of different cotton fabric content and clay powder loading on tensile strength, flexural strength, impact resistance, and thermal conductivity were systematically investigated. The results show that the addition of waste cotton fabric leads to a marked improvement in the mechanical properties with an efficient load transfer and stress distribution. The addition of clay powder also improves strength, stiffness, thermal stability, and flame retardancy. Tensile strength and impact strength increased from 12.5 MPa to 24.7 MPa and from 2.3 kJ/m² to 4.5 kJ/m², respectively, for materials with an optimal composition of 30 g cotton/3% clay powder component percentage ratio. For heat dissipation, thermal conductivities were from 0.12 to 0.28 W/m·K. With a medium content of clay (3%), better composite bonding and thermal properties were achieved, while high loadings (5%) resulted in agglomeration, thereby degrading the composite. These results indicate that recycled cotton fabric and clay powder have potential as eco-friendly reinforcements for sustainable, durable, and thermally insulating furniture material.
