    This research aims to enhance the reliability of fiber-reinforced-polymer (FRP) rods used in construction by evaluating the test results of 395 specimens and addressing the issue of variability inherent in the composite material on its tensile strength. Fiber reinforced polymer composites are known fortheir exceptional resistance to harsh conditions, impressive durability, and high tensile strength, making them increasingly popular in structural applications. A critical challenge addressed in this study is the inherent variability of composite materials and its impact on tensile strength, which directly influences the safety and durability of structural applications. The tensile strength tests on 103 CFRP, and 293 Hybrid glass-carbon FRP (HFRP) rod specimens were conducted employing the GB 30022-2013 standard.Subsequently, to ensure a robust analysis, the results were modeled using four statistical distributions: normal, lognormal, Weibull, and Gamma. A goodness-of-fit test was then applied to identify the most suitable model. The study reveals that the Weibull distribution model most accurately reflects the tensile strength of FRP rods of different diameters. Additionally, this research proposed
