| 總結: | The utilization of natural fibres such as kenaf into composites materials have been exploited globally especially for low-load-bearing applications. Bio-based cellulosic composites have advantages in terms of lower material cost and promote green technology in comparisons with composites from synthetic fibres which are relatively expensive and can contribute to environmental problems. In this research, bio-based composites were fabricated from several natural fibres and blends (l00% and 50/50% blends), initially converted into non-woven and woven fabric structures. Four different natural cellulosic fibres were utilized including kenaf, pineapple leaf, banana stem and coir. The composites were fabricated using epoxy, polyester, polypropylene and polyethylene resins. These composites were then tested for tensile strength and flexural strength. The results showed that for non-woven composites, the 100% pineapples fiber with epoxy resin gave the highest tensile strength while 100% kenaf fibres with epoxy resin gave the highest flexural strength. For both tensile and flexural strength results, the non-woven composites consisting of 100% coir fibres gave the lowest results. As for the woven composites, the 100% kenaf fibres with epoxy gave the highest tensile strength while the l00% kenaf fibres with polyester resin gave the highest flexural strength. Composites fabricated with epoxy resin gave the best tensile strength and flexural strength properties regardless of the types of fibres and fabric structure. |
