Advance knowledge in the field of oil and gas industry, will guide us towards the use of new materials, especially composite materials. Natural gas transmission pipelines as the longest energy materials transportation lines, can be one of the best capacities for the study and design of composite materials to be used. Also, Genetic algorithms provide a simple and almost generic method to solve complex optimization problems. Despite simplicity of it, genetic algorithm needs careful selection of settings like parent selection methods, mutation methods, population size to be able to find good solutions. Choosing unsuitable parameters and methods might result into longer program runs or even bad optimization results. In this paper, we will review the effect of fiber angle change in the mechanical properties of tubes made of four layered FW carbon - epoxy material studied under uniform internal pressure in natural gas transmission pipelines. Then will be calculated optimal fiber winding angle using Genetic Algorithms suitable for situations where in longitudinal strain, twist and longitudinal strain - twist simultaneously are Optimization factor. Finally, the optimal winding angle will be introduced. It is explained that this layering is as the symmetrical.
