| Summary: | Cone shells due to their special aerodynamic shape are the main component for air-space transport and submarine structures. The application of composite materials in these structures leads to achieving lower strength-to-weight ratios. Due to the type of application, most of these structures are under external pressure. The purpose of this paper is to achieve an empirical relationship between buckling pressures and the impact of various factors on the strain. The four factors that are going to be evaluated in this article are cone size, number of layers, number of layers of longitudinal reinforcement (Stringer), and number of circular reinforcement (Ring). To achieve this goal truncated composite cone samples, longitudinal and circular reinforcements are made of woven glass fiber with epoxy resin. The experiments are based on the RSM method in optimization. The results of this paper showed that the longitudinal reinforcements are not effective on buckling pressure. |
