Abstract

In the recent decades, the natural fibre (NF) has been one of the major interesting research subjects due to low cost, environmentally friendly, sustainability and available in abundance. This study will explore the kenaf core (KC) reinforced clay composite for roof tile application. In this research, there are varieties of size for KC will be used such as 20mm, 10 mm, 20 mesh and 40 mesh. This KC will be integrated with clay using the conventional method in fabricating a roof tile which includes process such as pressing, drying and firing. The samples are made in various ratios ranging from 10% to 40%. Additionally, it will have a dimensions of 300 mm × 280 mm × 7 mm, and will be compressed with a force of 14.95 kN by a hydraulic machine. The samples were dried for 14 days before going through the fire process at 100°C for roughly 5 hours, where they will be heated until stiff and solidified. Compression, flexural and thermal testing are used to investigate the sample's mechanical and physical properties. Thorough examination is performed with the information obtained by scanning electron microscopy (SEM). From the result, it was found that 20 mesh has only a slight difference of flexural strength performance than pure clay of 3.78%. It was also found that 30% KC of 40 mesh can withstand a force of 408.17 N. In addition, 40% KC of 10 mm has the highest value for heat resistance at 3.37°C. It can be concluded, integrating KC with clay enhance the heat resistance performance for the matrix material.
