Filament Wound Composite Plastic Tubes: Relationship Between Winding Structures аnd their Hydraulic аnd Mechanical PropertiesJovan Radulović A winding structure denotes the number of layers and the winding angle at which a reinforcing fiber is wound. regarding the tube longitudinal axis. Tubes with four different winding structures were produced by the filament winding technology of glass roving impregnated by a polyester resin system. Test tubes for hydraulic testing and ring specimens for mechanical investigation were produced by machining. Test tubes with four different winding structures were exposed to the influence of internal fluid hydraulic pressure. The burst pressure, radial deformation and radius displacement were determined. The ring specimens were exposed to tensile stress and their ultimate strength was determined. It is concluded that the winding structure has the essential influence on the hydraulic and mechanical properties of filament wound composite plastic tubes. Key words: composite materials, polymers, filament winding, winding structure, tube, mechanical properties.
