This experimental study explores novel reinforcement alternatives for composite materials, aiming to reduce dependence on synthetic fibers and fossil fuel derivatives through the utilization of vegetable fibers. A mechanical characterization was conducted on epoxy matrix composite materials reinforced with glass fiber and natural fiber fabric derived from bamboo cane and cotton. Specimens were fabricated and tested by ASTM D-3039 (tensile), ASTM D-7264 (flexural), and ASTM D-5628 (impact) standards. The optimal configuration consisted of one layer of glass fiber plus two layers of natural fiber fabric, oriented at 0°, vacuum laminated, and oven cured. This configuration exhibited a maximum tensile strength of 131.65 MPa, a maximum flexural strength of 124.61 MPa, and an impact resistance of 6.01 J. This hybrid material demonstrates potential applications in the automotive, construction, and furniture manufacturing industries. The results indicate that incorporating natural fibers into hybrid composites can significantly enhance mechanical properties, offering a sustainable alternative to conventional materials.

摘要

This experimental study explores novel reinforcement alternatives for composite materials, aiming to reduce dependence on synthetic fibers and fossil fuel derivatives through the utilization of vegetable fibers. A mechanical characterization was conducted on epoxy matrix composite materials reinforced with glass fiber and natural fiber fabric derived from bamboo cane and cotton. Specimens were fabricated and tested by ASTM D-3039 (tensile), ASTM D-7264 (flexural), and ASTM D-5628 (impact) standards. The optimal configuration consisted of one layer of glass fiber plus two layers of natural fiber fabric, oriented at 0°, vacuum laminated, and oven cured. This configuration exhibited a maximum tensile strength of 131.65 MPa, a maximum flexural strength of 124.61 MPa, and an impact resistance of 6.01 J. This hybrid material demonstrates potential applications in the automotive, construction, and furniture manufacturing industries. The results indicate that incorporating natural fibers into hybrid composites can significantly enhance mechanical properties, offering a sustainable alternative to conventional materials.
