Abstract

New test methods are proposed and evaluated for determination of the mode III delamination toughness of polymeric matrix composite materials. All methods use a split beam-type specimen. Different specimen geometries and various methods of load introduction and specimen constraint are considered. Initial assessments are performed via three dimensional finite element analyses and the most promising approaches are evaluated experimentally. Two different unidirectional carbon/ epoxy materials are considered. For either material, it is shown that the same mode III toughness is obtained from four different test configurations. This lends confidence that the tests are producing a material, rather than structural, property, and indicates that one of the configurations may prove to be a simple and accurate approach for determining the mode III delamination toughness of laminated composites.
