Background: Resin based composite materials, in spite of their numerous advantages are still limited in usage due to lack of certain mechanical properties. Lack of flexural strength is one such weakness. Reinforcing the resin composites with fibres have been shown to improve the strength. This study was conducted to assess the flexural strength of resin composite material reinforced with commercially available polyethylene woven fiber (Ribbond, U.S.A). Methodology: Two groups were made. Group 1 consisted of 30 resin based composite rectangular bar specimens of dimension 25×2×2 mm of length, width and height respectively. Group 2 consisted of 30 resin based composite bar specimens of similar dimension, but reinforced with polyethylene fibers at the middle of the specimen (neutral zone). All the specimens were subjected to three-point bend test and the maximum load at which fracture occurred were recorded and flexural strength were calculated. Results: The mean flexural strength with standard deviation of the group 1 and group 2 were 81.55 ±7.2 MPa and 95.04 ±2.6 MPa respectively. Conclusion: The study concluded that reinforcement of resin based composites with polyethylene, woven fibers significantly increased the flexural strength by 17%.
