The increasing emphasis on sustainable materials has resulted in heightened interest in natural fibre composites as environmentally friendly alter- natives to synthetic materials. Among these, date palm midrib fibres, which are abundant yet under utilised agricultural by-products, have significant potential for reinforcing polymer composites. In this study, composites with fibre-to-epoxy ratios of 0:100, 5:100, 10:100, and 15:100 were fabricated using the hand lay-up method to assess their mechanical properties and water absorption behaviour. The composite with a 15:100 ratio exhibited a 21.61% increase in tensile strength (55.19 MPa) and a 15.27% improvement in flexural strength (31.69 MPa) compared to pure epoxy, indicating enhanced load-bearing capabilities. However, the water absorption rate increased significantly from 0.41% to 7.21% owing to the hydrophilic nature of the fibres. These findings underscore the potential of date palm fibres as sustainable reinforcements for composites and highlight the necessity of advanced treatments to mitigate moisture sensitivity and optimise performance for broader applications.
