Natural fiber is recognized for having a lower density than synthetic fiber, as well as being cheaper, more plentiful, and most significantly, renewable. In Malaysia, the focus on waste fiber somehow produces an abundance of bio waste in the form of leaves, mainly composted or burned, thus wasting the good potential of fiber sources. The burning of the leaves will lead to environmental pollution problems. Many researchers have investigated the potential of this waste and have demanded the development of new materials with enhanced strength, stiffness, density, and cost-effectiveness. Due to the various applications of natural fibers, especially bamboo and kenaf, in several industries, they may be exposed to cyclic load based on their preferred applications. Thus, this study implemented a finite element method by using ANSYS to investigate the characteristics of the notch at crack tipopening angle for bamboo and kenaf woven fiber under quasi static loading as well as the deformation, strain, stress, and mode I stress intensity factor (SIF) criteria. This simulation focuses on the three types of woven orientations, which include 0°/90°, 30°/-60°, and 45°/-45°. The result shows that Kenaf fiber with a 0°/90° orientation showed good results in terms of strength compared to bamboo fiber, and among the three woven orientations, the 0°/90° orientation showed the highest stress intensity factor followed by 30°/-60° and 45°/-45° for both bamboo and kenaf fiber.
