Abstract
Natural fiber-reinforced composites (NFRCs) have gained significant attention for their array of advantages, including biodegradability, low density, and cost-effectiveness compared to synthetic fiber-reinforced composites. The surge in interest is driven by a global shift towards sustainability and eco-conscious practices across various industries. Consequently, there has been a significant increase in exploration and innovation within the realm of natural fiber composites, reflecting a collective effort towards more environmentally friendly material solutions. Industries such as automotive, construction, aviation, and aerospace are increasingly exploring the use of natural fiber composites. However, the flammability of natural fiber-reinforced composites is a major challenge that needs to be addressed. Wool fiber, known for its natural flame-retardant and self-extinguishing properties, has been widely used in the textile industry to produce apparel, but its use in composite production has been limited. This study explores the feasibility of using wool fibers for composite reinforcement, primarily for applications where fire resistance is required. In this work, wool woven fabric and unidirectional (UD) wool roving were used as preforms, and a bio-based resin was applied through resin infusion techniques to produce the composites. The prepared composite samples were subjected to tensile, three-point bending, thermal insulation, and fire-resistance experimental investigations. The results obtained from the experimental investigations indicate that wool fiber has promising potential as a reinforcement material in composite applications mostly where fire resistance is critical.
