The aim of this work is to develop a new hyperelastic and anisotropic material mimicking histological and mechanical features of healthy and aneurysmal arterial tissues. The target material is constituted by rhombic periodic lattices of hyperelastic fibres embedded into a soft elastomer membrane. Based on a previous theoretical work yielding to an optimized microstructural arrangement and mechanical behaviour, this study provides experimental advances concerning the manufacturing of new fibrous membranes. Their mechanical characterization under various loadings is presented.
