Failure and damage characterization of (±30°) biaxial braided composites under multiaxial stress states

This paper focuses on the mechanical characterization of (±30°) 2×2 biaxial braided composites under multiaxial stress states. Off-axis experiments in tension and compression were used to introduce multiaxial stresses in the material. The characterization was focused on nonlinear deformation and failure behavior: loading/unloading of the specimen was used to identify the mechanisms for nonlinear deformation and a high-speed-camera is used to...
