Impact strength, microstructure, and water absorption properties of kenaf/polyethylene terephthalate (PET) fiber-reinforced polyoxymethylene (POM) hybrid composites - Volume 28 Issue 16 - Yakubu Dan-mallam, Mohamad Zaki Abdullah, Puteri Sri Megat Yosuff The strength of kenaf fiber was garnered using the universal testing machine with a capacity of Core Bast Fig. Jute fiber is known as golden fiber of Bangladesh, jute is an important fiber of Eastern Indian and Bangladesh [10] . The performance of the composite depends on many factors such as structure, mechanical composition, physical properties, cell dimensions, microfibrillar angle etc. Bast fibers stems of kenaf (Hibiscus cannabinus, L.), a warm season tropical herbaceous annual plant extracted corresponding to different age, were dispersed into Poly‐ l ‐lactide (PLLA) matrix by melt blending followed by compression molding.

INTRODUCTION In historical records, the use of natural fiber composite had already been practiced International Journal of Integrated Engineering, Vol. The specifications of the kenaf fiber and epoxy used in this study ed in are list Table I ; Table II lists the properties of the type of epoxy resin (D.E.R. 2001). Fourier Transform Infrared (FTIR) Analysis of Untreated and Treated Fiber FTIR analysis was conducted to study the characteristics of the kenaf fibers, before and after bleaching treatment with hydrogen peroxide. of the kenaf composite. immersed kenaf fiber reinforced composite, may due to the damaged matrix, deteriorated interfacial adhesion, and bond strength, between matrix and fiber. kenaf fiber which is taken into consideration in this study is categorized in plant fibers. 331 . The results of thermal degradation showed about 80% weight loss for kenaf fiber between 300 and 350 C. The weight loss may This paper presents the energy absorption of woven kenaf fiber reinforced composite tubes subjected to axial compressive force. Kenaf Fibers and Composites covers the breadth of these exciting materials, from raw material preparation to application in a variety of products. 7. Kenaf fi bre-reinforced polymer composite is being fabricated from a variety of techniques. Kenaf fiber is a potentially outstanding reinforcing filler in thermo-plastic composites. of 3% NaOH fiber composite decreased after a soking time increase from 12 hours (63.2 MPa) to 24 hours (57.3 MPa). Composite materials combine the advantages of the two constituents. 7 No. In this paper we investigate the impact of increasing age of plant fiber on the corresponding composite. It offers a good performance compared to the random and short contributed fiber. As-received kenaf yarn is plain-weaved to form a woven kenaf mat.
