Internal geometry and mechanical behaviour of a 3D braided carbon/epoxy resin composite

Experimental characterization of a 3D braided carbon/epoxy resin composite, in terms of: (i) analysis of the 3D internal geometry; (ii) pre-fatigue quasi-static tensile mechanical characterization; (iii) analysis of the imparted damage initiation and development by acoustic emission analysis and microscopy; (iv) tensile-tensile fatigue life for different stress levels; (v) fatigue damage observation at different number of cycles by micro-CT analysis; and (vi) post-fatigue quasi-static residual tensile mechanical properties.
