The physical properties including the dimensional stability performance and the mechanical properties, such as the maximum bending stress, modulus of elasticity, tensile stress, and internal bonding strength of the experimental composite panels were determined. The specimens were first dried in an oven at 60 C for 24 h to remove the moisture in the specimen. ; Jayamani, E.; Heng, S.K. Sound absorption performance of natural kenaf fibres. In general, the elongation at break properties of the composites decreased when 10 wt% of kenaf fiber was added and the value was gradually reduced with more addition of kenaf fiber. The weight ratios of kenaf/bamboo were 30:70, 50:50 and 70:30. ; Chuah, C.H. It is made up of an inner woody core and an outer fibrous bark surrounding the core. Chandradass, J.; Kumar, M.R.

Physical and chemical characteristics of kenaf core and hemp core. Mariatti, J.; Nasir, M.; Ismail, H. Preliminary Studies of Woven Thermoplastic Composites. Physical and mechanical properties were examined. Kenaf is one of the allied fibres of jute and shows similar characteristics. Table 1 lists the properties. This paper reports the effect of alkali treatment conditions on the physical properties of kenaf fiber such as density, weight loss, diameter, cross sectional and fiber morphology. Kenaf/empty fruit bunch/polylactic acid (kenaf/EFB/PLA) hybrid biocomposites were prepared using hot press technique. Please let us know what you think of our products and services. PHYSICAL AND MECHANICAL PROPERTIES OF KENAF FIBER-NR BIOCOMPOSITE Kenaf is known as the natural fiber that content highly composition of cellulose and renewable fibers. Yang, W.; Li, Y. The hybridization of woven kenaf and bamboo showed an improvement in overall properties. Sound absorption coefficient of natural fibres hybrid reinforced polyester composites. Master’s Thesis, Universiti Sains Malaysia, Pulau Pinang, Malaysia, 1998. A. Physical Properties of Kenaf fibers The characteristics on geometrical properties of kenaf fibers were analyzed and data such as length, diameter and wall thickness were presented in the Table.3 Table 3: Physical Properties of Kenaf fibers Kenaf fiber Bleached Properties Retted fiber Degummed fiber fiber Length (mm) 5.86 3.25 3.25 The fibre was then sieved to obtain a size less than 500 µm using a Yahaya, R.; Sapuan, S.; Jawaid, M.; Leman, Z.; Zainudin, E. Effect of layering sequence and chemical treatment on the mechanical properties of woven kenaf–aramid hybrid laminated composites. Abstract. Elongation at break properties of pure PLA, PLA/unbleached kenaf fiber composites (UBC) and PLA/bleached kenaf fiber composites (BC) are shown in Figure 6. The plain woven kenaf fibre was prepared and cut to fabricate composite samples according to the ASTM standards. ; Hassan, A.; Dungani, R.; Hadiyane, A. ; Hamdan, S.
