Investigation of Mechanical and Thermal Properties of Bamboo Fiber Reinforced with Epoxidized Soybean Oil for Automotive Seat Bases 2024-01-5009

Bamboo fibers were used as reinforcement in hardened epoxy mixes altered with ethoxylated soybean oil (ESO) to enhance the mechanical and thermal qualities. Compared to a bio-based epoxy mix, the tensile strength and modulus of the laminate with 20% bamboo fiber were higher. During thermogravity analysis (TGA) evaluation, it was discovered that the rate of deterioration peak had been moved to a warmer temperature, indicating improved thermal durability of the aggregate over the base material. The dynamic mechanical evaluation of the bio-based composite anticipated increased storage modulus and greater glass transition temperatures. High fiber–matrix adherence was visible in scanning electron morphology (SEM). Measurements of the interfacial adhesion demonstrate the hydrophilicity of the bio-based reinforced composites. The binding and effective insemination of fibers is responsible for the fiber-reinforced composite’s durability. Higher rigidity and durability were generated because the lignocellulosic biomass adhered well to the low-viscosity resin. Moreover, research on adherence in composite materials reveals that the interfaces of composite materials with bamboo fibers are becoming more hydrophilic. Sufficient mechanical hardness, stiffness, and durability are realized for automobile and industrial purposes.
