N2 - Scientific interest in electrospinning as a technology to produce nanofibres andnanofibrous materials has increased dramatically in the last decade. Beneficialproperties of electrospun mats and single fibres enable wide range of applicability;especially in medicine as breathable and absorptive active wound dressingsenhancing healing process, and scaffolds mimicking natural cells environment,increasingly effective for tissue engineering. Other applications involve sensors,filtering media, and energy generation. Involvement of modelling tools to anticipateproperties of electrospun structures is exceptionally important due to relativelylow production ratio of electrospinning process and time consuming techniques tocharacterise electrospun materials. Models provide insight into structure’s behaviourwithout a necessity of building and testing multiple prototypes. They are savingyour time, materials and money, at the same time indicating which experimentsare worth performing to provide only interesting information in promising cases.In this work I present first mechanical Finite Elements model of structuredeveloped within electrospinning process that anticipates mechanical behaviourof the materials on the basis of single fibres properties and arrangement. Modelwas validated by testing three-dimensional electrospun material with tensile testing.You will also find here extensive information on properties of single nanofibres andtechniques for their measurement, properties of electrospun fabrics along withmechanisms taking part in their destruction imaged with Scanning ElectronMicroscopy.
