In the study, polyethylene methyl acrylate is a widely accepted material in the field of dentistry and medicine due to its excellent biological compatibility and easy manufacturing, although it shows lower mechanical properties. Therefore the present study was conducted to determine the bending properties of PMMA materials by enhancing PMMA with two different natural fibers (bamboo fibers and sioc). Non-continuous random fibers were used in three lengths (2, 6 and 12 mm) and three percentage points (3, 6 and 9% fracture weight) of both types of fiber. The results showed that bending coefficient, bending force and maximum shear stress were increased by increasing the fracture and length of the fibers for each of the fibers (bamboo and siwaak) to reach the maximum quantity in addition to the fraction of the thickness at 9% and length of 12 mm of fibers. The highest values ​​for bending and bending strength were maximum cut (10.09GPa), (112MPa), (6MPa) respectively, for composite samples with bamboo fibers, whereas for composite samples with siwaic fibers (9.71) GPa, (101MPa), 4.44MPa (9%) and length (12mm), and all composite samples reinforced with bamboo fiber showed higher curvature strength and curvature coefficient between the composite sample reinforced by siwak fibers.
