Abstract
Increasing need for materials with special features have brought various new inventions, one of the most promising hope for new material with special features and functionalities is composites materials. Thus, this study report an integration of zinc nanoparticles into kenaf/polyester polymer composite to introduce new behavior to the composite. The composite behaviors were compared for mechanical, thermal, moisture absorption and biodegradability properties. Prepared Zinc Oxide nanoparticles entrenched in the kenaf/polyestaer composites net structure through chemical bonds between kenaf/ZnO/polyester resin, existence of ZnO significantly influence the mechanical and thermals properties of composites. Thermal analysis based on (TGA) response revealed the integration of ZnO nanoparticles improved the thermal stability when thermal decomposition temperature beyond 3650 C. The thermal cracking decreased with present of ZnO and increase with kenaf content (layers). The modulus, Tensile strength, break at elongation, flexural modulus, flexural strength and impact strength of the composites with higher content kenaf/ZnO nanoparticle are 560 MPa, 58MPa, 1.8%, 1300 PMa, 68 MPa and 31 MPa, respectively. Thus, addition of kenaf layers and ZnO results in larger mechanical properties enhancement, the results of the contact angle show improvement in wetting of the fibres with addition of ZnO nanoparticles.

Summary
Environmental challenges today motivates scientist around the worldwide quest for new and yet biodegradable material [1]. Natural fibres polymer composites which have tendency to support the ability of polymer with sound mechanical and thermal properties yet biodegrade occupy a significant position in the world market [1,2]. The materials ease of manufacturing have allow researchers to use locally introduced inexpensive equipment and materials to produce and study the reinforced composite. Good reinforced polymer composite for different applications are produced [3]. The integration of natural materials such kenaf have attracted great interest in the development of low-cost, scalable and robust environmentally friendly composite [4]. The development will allow to obtain biodegradable material with mechanically capable which could fit into various applications.
