The effects of the winding process variables on the tensile properties of the filament wound structures were investigated. The ring specimens, consisted of the carbon fiber as reinforcement and the epoxy as resin, were fabricated through the filament winding technique for the measurement of the tensile properties. The fiber tensions and the fiber ends were considered as the winding process variables. The fiber tensions per fiber bundle varied from 4.9N to 29.4N. The fiber ends varied from 1 end to 6 ends. The tensile properties of the ring specimens were evaluated through the split disk test. The fiber volume fractions and the void contents for the ring specimens were also measured by the resin digestion. According to the results, the tensile properties of the ring specimens were sensitive to the fiber tensions and the fiber ends, which were closely related to the fiber volume fractions and the void contents. Therefore, the suitable selection for the winding process variables should be conducted to maximize the structural performance and to increase the productivity of the filament wound structures.
