The low interlaminar tensile strength of fiber reinforced composite materials presents serious challenges in the design of structures with a considerable radius of curvature, which is commonly found in a wide range of fields such as aeronautics, civil engineering, maritime industry, energy industry, among others. The objective of the present research was to analyze the interlaminar tensile strength, in the interlaminar layer of a material composed of fiberglass as reinforcement in nylon matrix, using a curved beam elaborated by additive manufacturing. To achieve this, tests were carried out according to ASTM Standard, and to determine which parameters significantly influence the failure of the composite material, variations were made in the thickness of the test specimens, which were manufactured following the criteria of the standard. The results obtained allow the assessment of interlaminar tensile strength and specimen behavior after failure.
