Interlaminar shear testing is a simple test on, easy to prepare,
polymer composite specimens that gives a measure of the strength
of the bond between fibers and matrix. Another common test for
polymer composites is flexure testing. The Instron® Modular Flexural and Interlaminar Shear Strength (ILSS) bend fixture system, with a range of interchangeable anvils, is suitable for testing to a number of international standards, including ASTM D2344, D790, EN 2562, EN 2563, ISO 14125, and ISO 14130.
