Modal Analysis of Composite Laminated Shell Reinforced by Crumbed Rubber Particles

The laminated of composite is a material made up of multiple layers of materials that are combined together to enhance mechanical and physical properties. These materials are used in a variety of applications, including aerospace, construction, and automotive, as they provide lightweight strength and flexibility. They are typically manufactured using techniques such as pressure and heat, which allow for strong adhesion between the layers. Laminated composite materials are ideal for applications that require high performance while minimizing weight. Two types of layer arrangements (symmetric and asymmetric) were used for the composite plates. The behavior of the separated plates using two models the symmetric and asymmetric model, with the aim of verifying the natural frequency results of the composite plates derived from finite element models analysis software that provides an integrated environment for designing and analyzing models. The results were used which include the natural frequency which is in proportion to the order of the symmetry max 1459.9Hz and min 257.95Hz as for the asymmetric arrangement it was max 1539.5Hz and min 241.57. Numerical analysis has proven to give good results at natural frequency. They are characterized by their toughness and flexibility, functioning as a waterproof coating and a strong insulator, making them ideal for use as a coating or adhesive.
