Multiaxial mechanical characterization of latex skin for morphing wing application

A morphing aircraft continuously adjusts its wing geometry to achieve optimal flight characteristics for a wide range of flight conditions. Research on morphing aircraft has focused on developing wings with 1 morphing degree of freedom “monomorphing”. However, nowadays the focus is on developing win...
