Paragraph starter

The selection of natural fibre-reinforced polymer composites (NFRPCs) for structural applications necessitates a thorough understanding of their performance under various loading conditions. While NFRPCs offer sustainability benefits, research indicates a significant susceptibility to low-velocity impact (LVI) loads, which can lead to internal damage and compromised structural integrity. This review highlights the importance of characterizing NFRPCs for LVI resistance and exploring strategies such as fibre hybridization or nanofiller incorporation to enhance their durability in demanding environments.
