RESEARCH ON STRUCTURE DESIGN AND PROCESSING TECHNOLOGYOF THIN-WALLED LINER COMPOSITE MATERIAL BARREL

Abstract

Abstract: In order to explore the application of carbon fiber reinforced composite materials in the design of single-barrel weapons, the structure design and process technology of thin-walled carbon fiber reinforced composite material launching tube were studied. Firstly, based on the elastic theory and grid theory, the thickness calculation models of thin-walled inner liner and carbon fiber reinforcement layer are established respectively. Secondly, based on the damage process of fiber reinforced composites, the failure mode of the composite barrel is analyzed, and the influence of the Tsai-Wu strength criterion (without distinguishing the failure form) and the Hashin strength criterion (distinguishing the failure form) on the design of composite barrel is discussed. Finally, the winding process flow of the composite material launching cylinder is expounded, and the influence of the laminating method and the winding tension on the filament winding process is analyzed. The research results can provide reference for the design and processing of composite material launch barrel and fiber reinforced composite cylinder structures.

Key words: thin-wall liner, carbon fiber, thickness calculation model, failure modes, the processing technology
