    Abstract

    Different test techniques for shear characterization are reassessed for their suitability for woven fabric composites. Considering the accuracy of results, ease of specimen fabrication, and simplicity of test technique, (±45) degree off-axis tension test is recommended for shear characterization of woven fabric composites. Calculations show that for typical E-glass/epoxy LY556 and T-300 carbon/epoxy LY556 two-dimensional orthogonal plain weave fabric laminates, the percentage shear contribution at failure is about 99 and 97–98, respectively. Hence, this test technique leads to a near pure shear condition in the test section for WF laminates.
