Fiber plants are overgrown in Indonesia as one of tropical countries. Natural fibers have many benefits, namely environmentally friendly, recyclable materials, flexible, and can be used as reinforcement in polymer composites. This research aimed to analyze the hardness, impact, and fire resistance properties on Sumberejo kenaf fiber reinforced epoxy composites with the fiber orientations of 0°/0°/0°/0° and 0°/90°/0°/90°. The kenaf fiber was alkaline treated before it was used as reinforcement and the composites were fabricated by Vacuum Assisted Resin Infusion technique. Furthermore, the composites surfaces, before and after flammability test, were observed. SNI 01-4449-2006 was used as density standard for fiber-board and these composites were categorized as High-Density Fiber-Boards. The 0°/0°/0°/0° and 0°/90°/0°/90° Sumberejo kenaf fiber reinforced epoxy composites had similar values of hardness and impact strength, which were (71.48 ± 0.69) HD and (72.4 ± 1.01) HD; and (32.61 ± 1.28) J/cm2 and (33.03 ± 1.05) J/cm2 respectively. Meanwhile, the 0°/90°/0°/90° composites had better combustion rate than the 0°/0°/0°/0° composites, with a value of (14.0 ± 0.2) mm/minutes. [ABSTRACT FROM AUTHOR]
