Application of synthetic fibres in composites has been raising environmental issues due to carbon emissions from the production site and reliability on non-renewable resources upon production. Hence, this research sets as a preliminary study to select suitable natural fibres to be hybridized with glass fibres for the development of sustainable and high-performance hybrid composites as potential alternative to conventional pultruded fibreglass composites in structural profile applications. In this study, analytical hierarchy process (AHP) was conducted to select the ideal natural fibre as reinforcement in the hybrid pultruded FRP composites suitable for structural applications. Hence, 13 natural fibre candidates were selected as alternatives and six criteria were chosen and analysed to select the best candidate for pultruded hybrid FRP. Criteria such as tensile strength, tensile modulus, density, cellulose content, elongation, and availability of fibres were assigned as the standard of selecting natural fibres for the application intended in this study. Among the 13 alternatives, kenaf was found to be the most suitable reinforcement for the application as it yielded the highest priority vector at 0.1. The results were then validated by carrying out sensitivity analysis to ensure kenaf is the most suitable material for the research.
合成纤维在复合材料中的应用引发了环境问题，这是由于生产现场的碳排放以及生产过程中对不可再生资源的依赖。因此，本研究作为一项初步研究，旨在选择合适的天然纤维与玻璃纤维进行混杂，以开发可持续的高性能混杂复合材料，作为结构型材应用中传统拉挤玻璃纤维复合材料的潜在替代品。在本研究中，采用层次分析法（AHP）来选择理想的天然纤维作为适合结构应用的混杂拉挤纤维增强塑料（FRP）复合材料的增强材料。因此，选择了13种天然纤维候选物作为替代品，并选择和分析了六个标准，以选出拉挤混杂FRP的最佳候选物。诸如拉伸强度、拉伸模量、密度、纤维素含量、伸长率和纤维可用性等标准被指定为选择本研究中预期应用的天然纤维的标准。在这13种替代品中，发现红麻是最适合该应用的增强材料，因为它产生了最高的优先向量，为0.1。然后通过进行敏感性分析来验证结果，以确保红麻是该研究最合适的材料。
