Abstract
The fiber reinforced composite material is widely used in the multi-industrial field where the weight reduction of the infrastructure is demanded because of their high specific modulus and specific strength. It has two main merits which are to cut down energy by reducing weight and to prevent explosive damage proceeding to the sudden bursting which is generated by the pressure leakage condition. Therefore, pressure vessels using this composite material in comparison with conventional metal vessels can be applied in the field such as defence industry, aerospace industry and rocket motor case where lightweight and the high pressure are demanded. In this paper, for non-linear finite element analysis of E-glass/epoxy filament wound composite pressure vessel receiving an internal pressure, the standard interpretation model is developed by using the ANSYS, general commercial software, which is verified as the accuracy and useful characteristic of the solution based on AutoLISP and ANSYS APDL. Both the preprocessor for doing exclusive analysis of filament wound composite pressure vessel and postprocessor that simplifies result of analysis have been developed to help the design engineers.
