    In this investigation, kenaf core fiber (KCF) reinforced polypropylene (PP) composite was prepared via extrusion and compression moulding. The effect of different ratio of KCF filler with PP on flexural properties of composite had been investigated. PP and KCF filler were prepared with different filler loading of 5, 10, 15, 20 and 25 wt% using twin-screw extruder at temperature 180 °C and rotor speed of 70 rpm, followed by compression moulding at the same temperature. The flexural tests were conducted to evaluate the flexural properties of the composite. The results obtained showed that the incorporation of KCF in PP increased the flexural strength and flexural modulus of the composite. The water absorption behaviour of the composite was also investigated. It was found that water absorption of composites increased with increasing of fiber content.

    Development of hybrid fiber reinforced composite as sustainable alternatives material for some industrial and engineering applications have gained significant interests over past few years. The combination of two different types of reinforcing elements in a single matrix system produce a hybrid composite with special features such as biodegradability, low cost, low specific weight, and in some cases, enhance the mechanical, thermal and water absorption properties compared to single-fiber reinforced composite. In this paper, the mechanical properties (tensile properties, flexural properties and impact strength), thermal expansion and water absorption behavior of hybrid fiber-reinforced composite were reviewed and reported.

    Carbonized natural filler can offer the production of low cost composites with an eco-friendliness value. The evolving field of electronics encourages the exploration of more functions and potential for carbonized natural filler, such as by modifying its surface chemistry. In this work, we have performed surface modification on carbonized wood fiber (CWF) prior to it being used as filler in the ethylene vinyl acetate (EVA) composite system. Zinc chloride (ZnCl2) with various contents (2 to 8 wt%) was used to surface modify the CWF and the effects of ZnCl2 composition on the surface morphology and chemistry of the CWF filler were investigated. Furthermore, the absorptive, mechanical, thermal, and electrical properties of the EVA composites containing CWF-ZnCl2 were also analyzed. SEM images indicated changes in the morphology of the CWF while FTIR analysis proved the presence of ZnCl2 functional groups in the CWF. EVA composites incorporating the CWF-ZnCl2 showed superior mechanical, thermal and electrical properties compared to the ones containing the CWF. The optimum content of ZnCl2 was found to be 6 wt%. Surface modification raised the electrical conductivity of the EVA/CWF composite through the development of conductive deposits in the porous structure of the CWF as a channel for ionic and electronic transfer between the CWF and EVA matrix.

    This work was aimed to study the composite of thermoplastic polypropylene (PP) and kenaf core fiber (KCF). More specifically, the effect of different KCF loading on mechanical properties of PP/KCF composite had been investigated. The fabrication of PP/KCF composite with filler loading of 5, 10, 15, 20, and 25 wt% was prepared by using co-rotating twin-screw extruder at temperature 180 ºC and rotor speed of 70 rpm. The mixing process then proceeded with compression molding at the same temperature to produce sheet composite, before the composite was cut into dumbbell specimens using a hydraulic press. All the samples were subjected to the tensile test to evaluate the mechanical properties of the composite. The results obtained showed that the increase in filler loadings increase tensile strength and modulus of the composite while decrease elongation at break. The highest tensile strength of composite recorded at 20 wt% of KCF loading, and the addition of more KCF after that resulting in a significant drop of tensile strength. To conclude, the mechanical properties of KCF reinforced polypropylene composite were influenced by filler loading.
