With the widespread use of composite materials, composite materials have started to be used in the production of pressure vessels. Composite materials are preferred for pressure vessels to be both light and durable. Lightness and durability are very important in pressure vessels used especially in the space and aviation industry and in areas such as diver boats. In applications, different productions are made with various additives in order to produce pressure vessels that are lighter and more durable. The aim of this thesis; The aim of this study is to investigate the surface deformation behavior of carbon composite tubes with different carbon nanotube additive ratios produced by filament winding technique and to investigate the effects of carbon nanotube additive ratios on axial, circumferential and shear stresses. Within the scope of this thesis, three samples with different carbon nanotube additive ratios were produced and these samples were tested under internal pressure and their surface shape changing behavior was investigated. In order to investigate the effect of carbon nanotube ratio on the surface shape change, these ratios were applied as 0%, 1% and 3%. All samples were produced with filament winding technique with a winding angle of ±55°. In the study, the effect of carbon nanotube additive on the axial, circumferential and shear stresses on the surface will be compared. In experimental studies, changes in shape were observed and recorded. As a result of the study, it was determined that the carbon nanotube additive increased the strength.
