In this research a novel preform for the reinforcement of tubular composite structures has been developed. The mentioned preform was woven from para aramid yarn in the tubular form. A mandrel was passed through a certain amount of tubular woven preform layer then impregnated with resin, cured in an oven and the resulting composite pipe was removed from the mandrel. By using the same para aramid yarn, filament wound composite pipes were also manufactured with the same production parameters. Axial and transverse compression behaviors of tubular woven preform reinforced composite pipes were compared with the ones that are manufactured by conventional filament winding method. The test results indicated that under transverse and axial compression, composite pipes developed in this study showed superior strength values than filament wound ones.
