Abstract

In recent years two notched beam flexure tests, the Iosipescu and the asymmetric four-point bending (AFPB) methods, have been proposed for the measurement of shear stress-strain behavior and shear strength of fiber reinforced composite materials. The methods have made significant inroads into the testing community for continuous, woven fabric and discontinuous fiber composites, and a test standard is being developed in ASTM Committee D-30. This paper describes the test methods and summarizes the results of a round-robin test program to define the within- and interlaboratory precision and bias.
