Hao, A.; Zhao, H.; Chen, J.Y. The analysis of void content showed that there was not much difference in the void content of hybrid composites, but there was a slight improvement compared to the woven kenaf composite. This study was conducted to find out the effects of different conditions of alkaline treatment in terms of the concentration of alkali solution and immersion time on the fiber properties. Preparation and Physical Properties of the Biocomposite, Cellulose Diacetate/Kenaf Fiber Sized with Poly(vinyl alcohol) Chang-Kyu Lee, Mi Suk Cho, In Hoi Kim, and Youngkwan Lee* Department of Chemical Engineering, Sungkyunkwan University, Suwon 440-746, Korea Jae Do Nam Kenaf fiber consists of cellulose (56–64 Wt.%), hemicellulose (21–35 Wt.%), lignin (8–14 Wt.%) and small amounts of extractives and ash , . Jawaid, M.; Abdul Khalil, H.P.S. Statistical analysis also showed the significant difference (95% level of significance) between the two types of board. We suggest the use of kenaf/bamboo hybrid composites for non-load bearing structures where noise control and sound absorbing properties are prime requirements. The fibre was chemically treated with both NaOH and Silane to compared its physical properties with the untreated fibre. 5% volume fraction of kenaf fiber exhibits the highest tensile modulus and flexural modulus in its composite materials.
