Advanced composite materials are increasingly used in hydrogen gas transport pipelines due to their excellent mechanical resistance, good corrosion resistance with lower density compared to steel material. The morphological properties the key parameters that gueven the mechanical behaviors of composite. The objectif of study is to incestynte the property-structure relationship using ANSYS Material Design, considering various morphological effects such as fiber fraction, fiber diameter, fiber distribution, and fiber material type. The analysis showed that the mechanical properties of the unidirectional composite are significantly affected by morphological parameters. In fact, smaller fiber diameters and higher volume fractions improve orthogonal stiffness and overall strength. Moreover The study discuss The effect of anisotropy variation of elastic properties for carbon-fiber reinforced polymers (CFRP) and glass-fiber reinforced polymers (GFRP). Specifically, CFRP composites exhibit a pronounced increase in The anisotropy with fiber volume fraction, reflecting their highly directional stiffnes. In contrast, GFRP composites show a decrease in this ratio as fiber volume fraction increases
