In past decade a new manufacturing and Design technology developed across the globe because of that it possible to manufacture and analyses a hybrid laminated composite plate which is used in the various applications like aerospace, marine, spacecraft application were its subjected to dynamic loading so it is necessary estimate the response of the system under free vibration. Aim of this paper is Dynamic analysis of laminated composite plate which is made of hybridization of carbon epoxy and glass epoxy material. Natural frequencies are evaluated by FEM with the help of abaqus software for of hybrid laminated composite plate. The Parameter like aspect ratio, fiber orientation, boundary condition and mesh size of the FEA elements and stacking sequence affects natural frequencies of the plate. A hybrid laminated composite in which carbon fiber on top as well as bottom and glass fiber in inters layer gives maximum natural frequency at any boundary condition. FEM uses first order shear deformation theory.

This paper presents a free vibration analysis of un-damped woven roving laminated composite plate using Classical Laminate Plate Theory (CLPT), for different boundary conditions. The fiber glass/epoxy woven roving laminated composite plates have been prepared using hand layup method. Three different fiber orientations have been considered for the fiber glass/epoxy laminated composite plate, having 50% each percentage by volume of glass and epoxy. Effects of fiber orientation on different mechanical properties such as density, hardness, impact strength and impact strength have been studied. Finite element modeling of the composite plates has been performed using different boundary conditions such as CCCC, CFCF, and CFFF and the fundamental frequencies obtained from the computational modeling have been compared with the available literature.
