A multi-section specimen has been designed and used for the direct measurement of the through-the-thickness tensile properties of three-dimensionally woven carbon/epoxy composites. Design optimization was conducted through the analysis of the stress fields using a two-dimensional boundary element method. three woven architectures were studied: a layer-to-layer angle interlock, a through-the-thickness angle interlock, and through-the-thickness orthogonal weave. All the preforms were infiltrated by the resin transfer molding technique. Several configurations of the multi-section specimen were tested and the results verified the findings of the numerical analyses.
