An NOL Multiaxial Fatigue Test Method has been developed to obtain information on the dynamic properties of plastics composite materials. The test method uses an NOL ring segment as the test specimen, and strain gages mounted on a specially prepared post are used to monitor the resistance of the specimen to the applied multiaxial load. Results obtained in a statistical experiment set-up to evaluate the test method show that it is capable of differentiating between materials andor fabrication parameters. In addition, reproducibility of the results is within the limits of accuracy relating to the winding, curing, and handling conditions imposed on the ring segments prior to testing. Author
