Comparative Analysis of Natural and Synthetic Fibre-Reinforced Composites: Mechanical Properties, Processing, and Sustainability Considerations
Abstract: The development of fibre-reinforced composites has significantly advanced engineering applications due to their excellent strength-to-weight ratio, corrosion resistance, and versatility. Synthetic fibres such as glass and carbon provide superior mechanical performance, but their production is energy-intensive and environmentally harmful. Natural fibres, including jute, flax, banana, and hemp, offer biodegradability, lower cost, and sustainability benefits, though they often fall short in strength and durability. Hybrid composites frequently demonstrate improved performance by …
