Abstract
This study investigates the mechanical properties of composite materials under tensile stress at different lamination angles, specifically 0 degrees and 90 degrees. The tensile tests measured parameters such as tensile stress and modulus of elasticity for various samples. The results indicate significant variations in mechanical properties based on the orientation of the fibers within the composite material. At 0 degrees, where fibers are aligned with the direction of the tensile force, some samples exhibited higher tensile stress and modulus of elasticity, with values reaching up to 1679.92 and 63.815, respectively. Conversely, at 90 degrees, where fibers are perpendicular to the tensile force, certain samples showed increased modulus of elasticity, with values as high as 2066.987. However, other samples demonstrated a decrease in mechanical properties at this orientation. These findings highlight the critical role of fiber orientation in determining the mechanical performance of composite materials, emphasizing the need for careful consideration of lamination angles in material design and engineering applications. The study underscores the importance of selecting appropriate fiber orientations to optimize the strength and stiffness of composite materials for specific applications, ensuring their reliability and efficiency in various engineering contexts.
