Test Methods for Characterization of Fiber Reinforced Composites

Abstract

Because of their nonisotropic and inhomogeneous nature, the testing of composites is more extensive than that of metals and is still evolving. Sample preparation and test methods are not fully developed or standardized for the industry. Test data depend upon the test method, specimen design and the composite void content. The work reported in this paper is in the direction of standardizing test methods for the industry and reviews the present status of test methods for characterization of fiber reinforced composites. Test methods available for tension, compression and shear are summarized and advantages and disadvantages of each are discussed. Recommendations have been made as to which test methods are acceptable for determining design allowables and which test methods are suitable only for comparative purposes and quality control. Where available, test data obtained from different test methods and/or different specimen designs have been discussed.
