A METHOD OF TEST FOR DETERMINING THE COMPRESSIVE PROPERTIES OF FILAMENT WOUND NOL RINGS,

Abstract

A mechanical fixture which can be used to determine the compressive properties of NOL rings has been developed. Use of the fixture enables the researcher to collect strength data on filament or roving wound rings, which data are important in the development of external pressure vessels. This method of test gives compressive strength and modulus values with low coefficients of variation. The data are representative of compressive strength; buckling of the ring specimens has been eliminated. As described herein, the tester can apply a maximum composite loading of 300,000 psi on a standard NOL ring configuration. (Author)
