Despite offering commendable strength and facile processing capabilities in the majority of equipment, this polymer is costly and requires additional modifications to be suitable for numerous practical applications . Therefore, an effective strategy for enhancing and reducing the cost of the material is to incorporate natural fibers, which have acquired popularity as a substitute for synthetic fibers. As a result, it is critical to incorporate these inexpensive natural fibers into biodegradable polymer (PLA) so as to effectively decrease manufacture costs by substituting a portion of the costly PLA with these inexpensive fibers without compromising the matrix polymer's biodegradability . The natural fiber composite sector is currently exhibiting significant interest in kenaf fibers due to their potential as reinforcements for polymers.
