The chemical composition of several non-woody plant fibers (bast fibers from flax, hemp, kenaf, jute; leaf fibers from sisal, abaca and curaua; and giant reed), which are used as raw materials for pulp and papermaking, has been evaluated. Particular attention was paid to the composition of the lipophilic compounds and the structure of the lignin polymer since they are important components of th...

This study investigates the effect of water absorption on flexural strength kenaf/ glass/unsaturated polyester (UPE) hybrid composite solid round rods used for insulating material applications. Three volume fractions kenaf/glass fibre 20:80 (KGPE20), 30:70 (KGPE30), and 40:60 (KGPE40) with three different arrangement profiles kenaf fibres were fabricated by using pultrusion technique aimed at s...

Kenaf fiber has been studied for biocomposites reinforcement due to its renewable and carbon neutrality. Meanwhile, polypropylene sheets are easily processed considered a prospective thermoplastic matrix source biocomposites. Hence, the combination of both materials is expected form an attractive biocomposite. This study aimed optimize permanganate treatment on tensile properties water absorpti...

In this study, various treated, untreated, and treated kenaf/glass fiber composites were fabricated using epoxy resin. A portion of kenaf fibers subjected to treatment with alkali, sub-portion was taken for benzoyl peroxide potassium permanganate prior composite fabrication. This on the material undertaken achieve improved modification interface between matrix bond. glass used enhancing mechani...

Kenaf fiber-polyester composites incorporated with powdered activated carbon (PAC) were prepared using the vacuum-assisted resin transfer molding (VARTM) process. The product demonstrates the electromagnetic interference (EMI) shielding function. The kenaf fibers were retted in a pressured reactor to remove the lignin and extractives in the fiber. The PAC was loaded into the freshly retted fibe...

This research was performed to evaluate the mechanical and thermal properties of sugar palm fiber (SPF)- kenaf (KF)-reinforced polypropylene (PP) composites. Sugar palm/kenaf successfully treated by benzoylation treatment. The hybridized bio-composites (PP/SPF/KF) were fabricated with overall 10 weight percentage (wt%) relatively three different fibers ratios between palm-treated kenaf-treated ...

Kenaf seed meal protein concentrate (KSPC) and lyophilized kenaf milky extract (KSMEPC) were obtained via alkaline extraction. The proximate compositions, amino acids functional properties of both concentrates compared. KSPC was found to be significantly higher in protein, essential non-essential but, lower lipid carbohydrate contents than KSMEPC. solubility, water absorption capacity denaturat...

Natural fiber is recognized for having a lower density than synthetic fiber, as well being cheaper, more plentiful, and most significantly, renewable. In Malaysia, the focus on waste somehow produces an abundance of bio in form leaves, mainly composted or burned, thus wasting good potential sources. The burning leaves will lead to environmental pollution problems. Many researchers have investig...
