Numerical Analysis of Multilayer Composite Under Free Vibration Conditions

Abstract

Laminated composites consist of multiple layers that are fused together to improve their mechanical and physical characteristics. Typically manufactured using pressure and heat techniques, ensuring a strong bond between the layers. Laminated composite materials are ideal for applications that require high performance while reducing weight. type of layer arrangements symmetric have been used in composite panels. The behavior of separated panels has been studied using the symmetric model to verify the natural frequency results of the composite panels, through the analysis of finite element models using software that provides an integrated environment for designing and analyzing models. Different diameters of rubber particles (1.8 mm, and 3.3 mm) used effect size on mechanical properties. The results related to the natural frequency were utilized, where the maximum symmetry recorded was 1058.1 Hz and the minimum was 166.68 Hz at a diameter of 1.8 mm, while the maximum was 975.56 Hz and the minimum was 153.84 Hz at a diameter of 3.3 mm. The numerical analyses showed good results regarding the natural frequency. These materials are characterized by their hardness and flexibility, making them suitable as a waterproof coating and effective insulator, which enhances their use as a coating or adhesive.
