ABSTRACT
Kenaf fibers are used as a reinforcement for plastic and synthetic products, cosmetics, organic fillers, and medicine. One of the common natural fibers used in reinforcement in polymer matrix composites is kenaf, and it is a necessary resource of cellulose composites and the other industrial applications. The cellulose fiber structure must not be infected or damage during the elimination of noncellulosic polysaccharides, since the quality of fiber produced depends on the method of the extraction of fiber. O. M. L. Asumani et al. studied the combination of both treatments of alkali-silane on kenaf-based cellulose fiber-reinforced polypropylene composites, which significantly enhanced the tensile and flexural properties and was notably better than those gained from either alkali and silane treatment alone. Polylactic acid is one of the famous thermoplastics which are used in packaging materials and has similar mechanical properties to other petroleum-based polymers, like polyethylene, polystyrene, polypropylene, and polyethylene terephthalate.
