Physical and damping properties of kenaf fibre filled natural rubber/thermoplastic polyurethane composites


A.M., Noor Azammi and Salit, Mohd Sapuan and Ishak, Mohamad Ridzwan and Hameed Sultan, Mohamed Thariq (2020) Physical and damping properties of kenaf fibre filled natural rubber/thermoplastic polyurethane composites. Defence Technology, 16 (1). 29 - 34. ISSN 2214-9147


The paper presents the investigation of the effect of alkaline treatment of sodium hydroxide (NaOH) on physical and dynamic mechanical analysis (DMA) viscoelastic properties of kenaf fibre filled natural rubber (NR)/thermoplastic polyurethane (TPU) composites. The treated kenaf fiber, NR and TPU were weighed and proportioned according to the required compositions and were blended using hot mixed Brabender machine. The polymer composites were then fabricated using the hot press to form a sample board. The sample was cut and prepared and water absorption, density, thickness swelling and DMA tests were performed. As far as physical properties are concerned, composites with the highest NR amount of shows the best results, which indicates good fiber bonding adhesion. The polymer composites with the highest amount of TPU shows the highest damping properties at high temperature.
