Abstract

Natural fibers have their own properties that have high strength, environmentally friendly and lower cost compared to synthetic fibers. Therefore, many manufacturing areas such as aircraft and automobiles use natural fibers as reinforcement to produce high strength composite materials. In addition, there are many research focusing on natural fibre - based composites in the form of lamina, but there is no specific study on the kenaf core in the use of the thermal insulation. Therefore, the purpose of this study is to investigate the different size of the kenaf core using intraply concept. The purpose of the study was to develop intraply composite by combining kenaf core as reinforcement with different kenaf core parameters of size by using polyurethane and natural rubber as matrix. Furthermore, the sample surface morphology tested was analyzed using scanning electron microscope (SEM). Ultimately, this research is expected to have the best thermal insulation from kenaf core which will contribute to high performance in the mechanical and physical properties of the intraply composite system.in this research also helped to make the best design to meet the demand of today's manufactures by reducing the weight and transportation cost. The best layup from the research is CCC ( 40 mesh) which is 31 .2 % better than the original PU and tend to become the good thermal insulation compare to other sample. This sample is light in weight and also the price is reasonable. Lastly, usage of natural fibre reduced weight and more recyclable.
