Thin wall and thick wall filament wound polymeric composite tubes: Mechanical characteristics caused by internal hydraulic pressure
Military Technical Institute - MTI, Belgrade
Two groups of so-called "thin wall" test tubes (wall thickness less than 2 mm) and two groups of so-called "thick wall" test tubes (wall thickness more than 2 mm) of the same internal diameter were produced by the filament winding technology using glass roving and a polyester resin system. The mentioned test tubes were exposed to the influence of internal hydraulic pressure and their mechanical characteristics were investigated. The radial deformations of four groups of filament wound test tubes were measured by strain gauges and internal hydraulic pressure was recorded by a piezoelectric pressure converter. The elastic characteristics i.e. elastic deformations and hydraulic pressures at the elastic limit were determined. The testing processes were ended by determining the final properties i.e. radial deformations and hydraulic pressure at the moment of burst of two groups of "thin wall" and two groups of "thick wall" test tubes.
