This research suggests an appropriate test method for the evaluation of tensile properties of filament wound structures by comparing the results of ring test and tensile coupon test. The research results showed that the tensile strength of each test method was influenced by the specimen shape. the continuity of fibers. and stress concentration in the specimen. The tensile strength of a ring specimen showed better agreement with the theoretical value obtained from the rule of mixtures than that of a coupon specimen because the stress concentration in a coupon specimen due to gripping action was more severe than that due to split disk edges in a ring specimen. The tensile modulus was influenced by the curvature in the coupon specimen and by the friction between the specimen and fixture surface in the ring specimen. With the aid of suitable data processing. the measured modulus agreed well with the theoretical value in the ring test. The ring test was better than the tensile coupon test for the quantitative characterization of tensile properties of filament wound structures.
