This paper presents the parametric analysis of ply properties on composite cylinder design for satellites. The composite cylinder is modelled as a sandwich construction type with honeycomb as a core and a multi-layer laminate composed of CFRP (Carbon Fiber Reinforced Plastics) plies as a skin. A design algorithm is developed with the help of C programs interfaced with IDEAS EDS for finite element analysis. During simulation, the different subsystems and panels are idealised as a mass load applied at their centre of gravities. Different parameters such as aspect ratio, ply orientation and number of plies have been analysed for arriving optimum design satisfying the static and frequency constraints. This approach is well implemented in the design and development of composite cylinder for different satellites and their validation with tests are under development.
