 This study aims to identify the most suitable natural fibers in Jordan for use in natural fiber composites by evaluating their physical and mechanical properties according to ASTM standards. The results show that several natural fibers have better characteristics than commonly used fibers worldwide and suggest the development of a proper evaluation methodology for selecting new natural types for green products.
