Abstract
Local tissue defects inevitably form in fiber-reinforced composites during the molding process, which may affect their sound transmission performance. This study investigates the influence of local tissue defects on the sound transmission properties of composite laminates through analytical and numerical models. A two-dimensional axisymmetric model of composite laminates was established based on the numerical approach, incorporating the anisotropic characteristics of the laminates. Parametric scanning was conducted to analyze the effects of defect filler materials, size, position, and thickness on sound transmission performance. The generation of transmission loss peaks was further elucidated through displacement amplitude contour maps. The results demonstrate that the defect filler material exhibits the most pronounced influence on sound transmission performance, while the position and thickness of defects exhibit weaker effects. In contrast, the radius of local defects shows a strong correlation with structural sound transmission performance.
